-# skopeoimage
-
-## Overview
-
-This directory contains the Containerfiles necessary to create the skopeoimage container
-images that are housed on quay.io under the skopeo account.  All repositories where
-the images live are public and can be pulled without credentials.  These container images are secured and the
-resulting containers can run safely with privileges within the container.
-
-The container images are built using the latest Fedora and then Skopeo is installed into them.
-The PATH in the container images is set to the default PATH provided by Fedora.  Also, the
-ENTRYPOINT and the WORKDIR variables are not set within these container images, as such they
-default to `/`.
-
-The container images are:
-
-  * `quay.io/containers/skopeo:v<version>` and `quay.io/skopeo/stable:v<version>` -
-    These images are built daily.  These images are intended contain an unchanging
-    and stable version of skopeo.  For the most recent `<version>` tags (`vX`,
-    `vX.Y`, and `vX.Y.Z`) the image contents will be updated daily to incorporate
-    (especially) security updates.  For build details, please[see the configuration
-    file](stable/Containerfile).
-  * `quay.io/containers/skopeo:latest` and `quay.io/skopeo/stable:latest` -
-    Built daily using the same Containerfile as above.  The skopeo version
-    will remain the "latest" available in Fedora, however the other image
-    contents may vary compared to the version-tagged images.
-  * `quay.io/skopeo/testing:latest` - This image is built daily, using the
-    latest version of Skopeo that was in the Fedora `updates-testing` repository.
-    The image is Built with [the testing Containerfile](testing/Containerfile).
-  * `quay.io/skopeo/upstream:latest` - This image is built daily using the latest
-    code found in this GitHub repository.  Due to the image changing frequently,
-    it's not guaranteed to be stable or even executable.  The image is built with
-    [the upstream Containerfile](upstream/Containerfile).
-
-
-## Sample Usage
-
-Although not required, it is suggested that [Podman](https://github.com/containers/podman) be used with these container images.
-
-```
-# Get Help on Skopeo
-podman run docker://quay.io/skopeo/stable:latest --help
-
-# Get help on the Skopeo Copy command
-podman run docker://quay.io/skopeo/stable:latest copy --help
-
-# Copy the Skopeo container image from quay.io to
-# a private registry
-podman run docker://quay.io/skopeo/stable:latest copy docker://quay.io/skopeo/stable docker://registry.internal.company.com/skopeo
-
-# Inspect the fedora:latest image
-podman run docker://quay.io/skopeo/stable:latest inspect --config docker://registry.fedoraproject.org/fedora:latest  | jq
-```
+The skopeo container image build context and automation have been
+moved to [https://github.com/containers/image_build/tree/main/skopeo](https://github.com/containers/image_build/tree/main/skopeo)

+#### Additional prerequisites
+
+In order to dynamically link against system libraries and avoid compilation errors the ```CGO_ENABLED='1'``` flag must be enabled. You can easily check by ```go env | grep CGO_ENABLED```.
+
+An alternative would be to set the `BUILDTAGS=containers_image_openpgp` (this removes the dependency on `libgpgme` and its companion libraries).
+
+### Cross-compilation
+
+For cross-building skopeo, use the command `make bin/skopeo.OS.ARCH`, where OS represents
+the target operating system and ARCH stands for the desired architecture. For instance,
+to build skopeo for RISC-V 64-bit Linux, execute:
+
+```bash
+make bin/skopeo.linux.riscv64

+
+- #125: Fixes issue with module path for v3
+
+## 3.0.0 (2019-09-12)
+
+This is a major release of the semver package which includes API changes. The Go
+API is compatible with ^1. The Go API was not changed because many people are using
+`go get` without Go modules for their applications and API breaking changes cause
+errors which we have or would need to support.
+
+The changes in this release are the handling based on the data passed into the
+functions. These are described in the added and changed sections below.
+
+### Added
+
+- StrictNewVersion function. This is similar to NewVersion but will return an
+  error if the version passed in is not a strict semantic version. For example,
+  1.2.3 would pass but v1.2.3 or 1.2 would fail because they are not strictly
+  speaking semantic versions. This function is faster, performs fewer operations,
+  and uses fewer allocations than NewVersion.
+- Fuzzing has been performed on NewVersion, StrictNewVersion, and NewConstraint.
+  The Makefile contains the operations used. For more information on you can start
+  on Wikipedia at https://en.wikipedia.org/wiki/Fuzzing
+- Now using Go modules
+
+### Changed
+
+- NewVersion has proper prerelease and metadata validation with error messages
+  to signal an issue with either of them
+- ^ now operates using a similar set of rules to npm/js and Rust/Cargo. If the
+  version is >=1 the ^ ranges works the same as v1. For major versions of 0 the
+  rules have changed. The minor version is treated as the stable version unless
+  a patch is specified and then it is equivalent to =. One difference from npm/js
+  is that prereleases there are only to a specific version (e.g. 1.2.3).
+  Prereleases here look over multiple versions and follow semantic version
+  ordering rules. This pattern now follows along with the expected and requested
+  handling of this packaged by numerous users.
+
+## 1.5.0 (2019-09-11)
+
+### Added
+
+- #103: Add basic fuzzing for `NewVersion()` (thanks @jesse-c)
+
+### Changed
+
+- #82: Clarify wildcard meaning in range constraints and update tests for it (thanks @greysteil)
+- #83: Clarify caret operator range for pre-1.0.0 dependencies (thanks @greysteil)
+- #72: Adding docs comment pointing to vert for a cli
+- #71: Update the docs on pre-release comparator handling
+- #89: Test with new go versions (thanks @thedevsaddam)
+- #87: Added $ to ValidPrerelease for better validation (thanks @jeremycarroll)
+
+### Fixed
+
+- #78: Fix unchecked error in example code (thanks @ravron)
+- #70: Fix the handling of pre-releases and the 0.0.0 release edge case
+- #97: Fixed copyright file for proper display on GitHub
+- #107: Fix handling prerelease when sorting alphanum and num 
+- #109: Fixed where Validate sometimes returns wrong message on error

+
+## Release 1.2.0 (2016-11-04)
+
+### Added
+
+- #20: Added MustParse function for versions (thanks @adamreese)
+- #15: Added increment methods on versions (thanks @mh-cbon)
+
+### Fixed
+
+- Issue #21: Per the SemVer spec (section 9) a pre-release is unstable and
+  might not satisfy the intended compatibility. The change here ignores pre-releases
+  on constraint checks (e.g., ~ or ^) when a pre-release is not part of the
+  constraint. For example, `^1.2.3` will ignore pre-releases while
+  `^1.2.3-alpha` will include them.
+
+## Release 1.1.1 (2016-06-30)
+
+### Changed
+
+- Issue #9: Speed up version comparison performance (thanks @sdboyer)
+- Issue #8: Added benchmarks (thanks @sdboyer)
+- Updated Go Report Card URL to new location
+- Updated Readme to add code snippet formatting (thanks @mh-cbon)
+- Updating tagging to v[SemVer] structure for compatibility with other tools.
+
+## Release 1.1.0 (2016-03-11)
+
+- Issue #2: Implemented validation to provide reasons a versions failed a
+  constraint.
+
+## Release 1.0.1 (2015-12-31)
+
+- Fixed #1: * constraint failing on valid versions.
+
+## Release 1.0.0 (2015-10-20)

+# SemVer
+
+The `semver` package provides the ability to work with [Semantic Versions](http://semver.org) in Go. Specifically it provides the ability to:
+
+* Parse semantic versions
+* Sort semantic versions
+* Check if a semantic version fits within a set of constraints
+* Optionally work with a `v` prefix

+
+## Package Versions
+
+Note, import `github.com/github.com/Masterminds/semver/v3` to use the latest version.
+
+There are three major versions fo the `semver` package.
+
+* 3.x.x is the stable and active version. This version is focused on constraint
+  compatibility for range handling in other tools from other languages. It has
+  a similar API to the v1 releases. The development of this version is on the master
+  branch. The documentation for this version is below.
+* 2.x was developed primarily for [dep](https://github.com/golang/dep). There are
+  no tagged releases and the development was performed by [@sdboyer](https://github.com/sdboyer).
+  There are API breaking changes from v1. This version lives on the [2.x branch](https://github.com/Masterminds/semver/tree/2.x).
+* 1.x.x is the original release. It is no longer maintained. You should use the
+  v3 release instead. You can read the documentation for the 1.x.x release
+  [here](https://github.com/Masterminds/semver/blob/release-1/README.md).
+
+## Parsing Semantic Versions
+
+There are two functions that can parse semantic versions. The `StrictNewVersion`
+function only parses valid version 2 semantic versions as outlined in the
+specification. The `NewVersion` function attempts to coerce a version into a
+semantic version and parse it. For example, if there is a leading v or a version
+listed without all 3 parts (e.g. `v1.2`) it will attempt to coerce it into a valid
+semantic version (e.g., 1.2.0). In both cases a `Version` object is returned
+that can be sorted, compared, and used in constraints.
+
+When parsing a version an error is returned if there is an issue parsing the
+version. For example,
+
+    v, err := semver.NewVersion("1.2.3-beta.1+build345")
+
+The version object has methods to get the parts of the version, compare it to
+other versions, convert the version back into a string, and get the original
+string. Getting the original string is useful if the semantic version was coerced
+into a valid form.
+
+## Sorting Semantic Versions
+
+A set of versions can be sorted using the `sort` package from the standard library.
+For example,
+
+```go
+raw := []string{"1.2.3", "1.0", "1.3", "2", "0.4.2",}
+vs := make([]*semver.Version, len(raw))
+for i, r := range raw {
+    v, err := semver.NewVersion(r)
+    if err != nil {
+        t.Errorf("Error parsing version: %s", err)
+    }
+
+    vs[i] = v
+}
+
+sort.Sort(semver.Collection(vs))
+```
+
+## Checking Version Constraints
+
+There are two methods for comparing versions. One uses comparison methods on
+`Version` instances and the other uses `Constraints`. There are some important
+differences to notes between these two methods of comparison.
+
+1. When two versions are compared using functions such as `Compare`, `LessThan`,
+   and others it will follow the specification and always include prereleases
+   within the comparison. It will provide an answer that is valid with the
+   comparison section of the spec at https://semver.org/#spec-item-11
+2. When constraint checking is used for checks or validation it will follow a
+   different set of rules that are common for ranges with tools like npm/js
+   and Rust/Cargo. This includes considering prereleases to be invalid if the
+   ranges does not include one. If you want to have it include pre-releases a
+   simple solution is to include `-0` in your range.
+3. Constraint ranges can have some complex rules including the shorthand use of
+   ~ and ^. For more details on those see the options below.
+
+There are differences between the two methods or checking versions because the
+comparison methods on `Version` follow the specification while comparison ranges
+are not part of the specification. Different packages and tools have taken it
+upon themselves to come up with range rules. This has resulted in differences.
+For example, npm/js and Cargo/Rust follow similar patterns while PHP has a
+different pattern for ^. The comparison features in this package follow the
+npm/js and Cargo/Rust lead because applications using it have followed similar
+patters with their versions.
+
+Checking a version against version constraints is one of the most featureful
+parts of the package.
+
+```go
+c, err := semver.NewConstraint(">= 1.2.3")
+if err != nil {
+    // Handle constraint not being parsable.
+}
+
+v, err := semver.NewVersion("1.3")
+if err != nil {
+    // Handle version not being parsable.
+}
+// Check if the version meets the constraints. The a variable will be true.
+a := c.Check(v)
+```
+
+### Basic Comparisons
+
+There are two elements to the comparisons. First, a comparison string is a list
+of space or comma separated AND comparisons. These are then separated by || (OR)
+comparisons. For example, `">= 1.2 < 3.0.0 || >= 4.2.3"` is looking for a
+comparison that's greater than or equal to 1.2 and less than 3.0.0 or is
+greater than or equal to 4.2.3.
+
+The basic comparisons are:
+
+* `=`: equal (aliased to no operator)
+* `!=`: not equal
+* `>`: greater than
+* `<`: less than
+* `>=`: greater than or equal to
+* `<=`: less than or equal to
+
+### Working With Prerelease Versions
+
+Pre-releases, for those not familiar with them, are used for software releases
+prior to stable or generally available releases. Examples of prereleases include
+development, alpha, beta, and release candidate releases. A prerelease may be
+a version such as `1.2.3-beta.1` while the stable release would be `1.2.3`. In the
+order of precedence, prereleases come before their associated releases. In this
+example `1.2.3-beta.1 < 1.2.3`.
+
+According to the Semantic Version specification prereleases may not be
+API compliant with their release counterpart. It says,
+
+> A pre-release version indicates that the version is unstable and might not satisfy the intended compatibility requirements as denoted by its associated normal version.
+
+SemVer comparisons using constraints without a prerelease comparator will skip
+prerelease versions. For example, `>=1.2.3` will skip prereleases when looking
+at a list of releases while `>=1.2.3-0` will evaluate and find prereleases.
+
+The reason for the `0` as a pre-release version in the example comparison is
+because pre-releases can only contain ASCII alphanumerics and hyphens (along with
+`.` separators), per the spec. Sorting happens in ASCII sort order, again per the
+spec. The lowest character is a `0` in ASCII sort order
+(see an [ASCII Table](http://www.asciitable.com/))
+
+Understanding ASCII sort ordering is important because A-Z comes before a-z. That
+means `>=1.2.3-BETA` will return `1.2.3-alpha`. What you might expect from case
+sensitivity doesn't apply here. This is due to ASCII sort ordering which is what
+the spec specifies.
+
+### Hyphen Range Comparisons
+
+There are multiple methods to handle ranges and the first is hyphens ranges.
+These look like:
+
+* `1.2 - 1.4.5` which is equivalent to `>= 1.2 <= 1.4.5`
+* `2.3.4 - 4.5` which is equivalent to `>= 2.3.4 <= 4.5`
+
+### Wildcards In Comparisons
+
+The `x`, `X`, and `*` characters can be used as a wildcard character. This works
+for all comparison operators. When used on the `=` operator it falls
+back to the patch level comparison (see tilde below). For example,
+
+* `1.2.x` is equivalent to `>= 1.2.0, < 1.3.0`
+* `>= 1.2.x` is equivalent to `>= 1.2.0`
+* `<= 2.x` is equivalent to `< 3`
+* `*` is equivalent to `>= 0.0.0`
+
+### Tilde Range Comparisons (Patch)
+
+The tilde (`~`) comparison operator is for patch level ranges when a minor
+version is specified and major level changes when the minor number is missing.
+For example,
+
+* `~1.2.3` is equivalent to `>= 1.2.3, < 1.3.0`
+* `~1` is equivalent to `>= 1, < 2`
+* `~2.3` is equivalent to `>= 2.3, < 2.4`
+* `~1.2.x` is equivalent to `>= 1.2.0, < 1.3.0`
+* `~1.x` is equivalent to `>= 1, < 2`
+
+### Caret Range Comparisons (Major)
+
+The caret (`^`) comparison operator is for major level changes once a stable
+(1.0.0) release has occurred. Prior to a 1.0.0 release the minor versions acts
+as the API stability level. This is useful when comparisons of API versions as a
+major change is API breaking. For example,
+
+* `^1.2.3` is equivalent to `>= 1.2.3, < 2.0.0`
+* `^1.2.x` is equivalent to `>= 1.2.0, < 2.0.0`
+* `^2.3` is equivalent to `>= 2.3, < 3`
+* `^2.x` is equivalent to `>= 2.0.0, < 3`
+* `^0.2.3` is equivalent to `>=0.2.3 <0.3.0`
+* `^0.2` is equivalent to `>=0.2.0 <0.3.0`
+* `^0.0.3` is equivalent to `>=0.0.3 <0.0.4`
+* `^0.0` is equivalent to `>=0.0.0 <0.1.0`
+* `^0` is equivalent to `>=0.0.0 <1.0.0`
+
+## Validation
+
+In addition to testing a version against a constraint, a version can be validated
+against a constraint. When validation fails a slice of errors containing why a
+version didn't meet the constraint is returned. For example,
+
+```go
+c, err := semver.NewConstraint("<= 1.2.3, >= 1.4")
+if err != nil {
+    // Handle constraint not being parseable.
+}
+
+v, err := semver.NewVersion("1.3")
+if err != nil {
+    // Handle version not being parseable.
+}
+
+// Validate a version against a constraint.
+a, msgs := c.Validate(v)
+// a is false
+for _, m := range msgs {
+    fmt.Println(m)
+
+    // Loops over the errors which would read
+    // "1.3 is greater than 1.2.3"
+    // "1.3 is less than 1.4"
+}
+```

+Package semver provides the ability to work with Semantic Versions (http://semver.org) in Go.
+
+Specifically it provides the ability to:
+
+  - Parse semantic versions
+  - Sort semantic versions
+  - Check if a semantic version fits within a set of constraints
+  - Optionally work with a `v` prefix
+
+# Parsing Semantic Versions
+
+There are two functions that can parse semantic versions. The `StrictNewVersion`
+function only parses valid version 2 semantic versions as outlined in the
+specification. The `NewVersion` function attempts to coerce a version into a
+semantic version and parse it. For example, if there is a leading v or a version
+listed without all 3 parts (e.g. 1.2) it will attempt to coerce it into a valid
+semantic version (e.g., 1.2.0). In both cases a `Version` object is returned
+that can be sorted, compared, and used in constraints.
+
+When parsing a version an optional error can be returned if there is an issue
+parsing the version. For example,
+
+	v, err := semver.NewVersion("1.2.3-beta.1+b345")
+
+The version object has methods to get the parts of the version, compare it to
+other versions, convert the version back into a string, and get the original
+string. For more details please see the documentation
+at https://godoc.org/github.com/Masterminds/semver.
+
+# Sorting Semantic Versions
+
+A set of versions can be sorted using the `sort` package from the standard library.
+For example,
+
+	    raw := []string{"1.2.3", "1.0", "1.3", "2", "0.4.2",}
+	    vs := make([]*semver.Version, len(raw))
+		for i, r := range raw {
+			v, err := semver.NewVersion(r)
+			if err != nil {
+				t.Errorf("Error parsing version: %s", err)
+			}
+
+			vs[i] = v
+		}
+
+		sort.Sort(semver.Collection(vs))
+
+# Checking Version Constraints and Comparing Versions
+
+There are two methods for comparing versions. One uses comparison methods on
+`Version` instances and the other is using Constraints. There are some important
+differences to notes between these two methods of comparison.
+
+ 1. When two versions are compared using functions such as `Compare`, `LessThan`,
+    and others it will follow the specification and always include prereleases
+    within the comparison. It will provide an answer valid with the comparison
+    spec section at https://semver.org/#spec-item-11
+ 2. When constraint checking is used for checks or validation it will follow a
+    different set of rules that are common for ranges with tools like npm/js
+    and Rust/Cargo. This includes considering prereleases to be invalid if the
+    ranges does not include on. If you want to have it include pre-releases a
+    simple solution is to include `-0` in your range.
+ 3. Constraint ranges can have some complex rules including the shorthard use of
+    ~ and ^. For more details on those see the options below.
+
+There are differences between the two methods or checking versions because the
+comparison methods on `Version` follow the specification while comparison ranges
+are not part of the specification. Different packages and tools have taken it
+upon themselves to come up with range rules. This has resulted in differences.
+For example, npm/js and Cargo/Rust follow similar patterns which PHP has a
+different pattern for ^. The comparison features in this package follow the
+npm/js and Cargo/Rust lead because applications using it have followed similar
+patters with their versions.
+
+Checking a version against version constraints is one of the most featureful
+parts of the package.
+
+	c, err := semver.NewConstraint(">= 1.2.3")
+	if err != nil {
+	    // Handle constraint not being parsable.
+	}
+
+	v, err := semver.NewVersion("1.3")
+	if err != nil {
+	    // Handle version not being parsable.
+	}
+	// Check if the version meets the constraints. The a variable will be true.
+	a := c.Check(v)
+
+# Basic Comparisons
+
+There are two elements to the comparisons. First, a comparison string is a list
+of comma or space separated AND comparisons. These are then separated by || (OR)
+comparisons. For example, `">= 1.2 < 3.0.0 || >= 4.2.3"` is looking for a
+comparison that's greater than or equal to 1.2 and less than 3.0.0 or is
+greater than or equal to 4.2.3. This can also be written as
+`">= 1.2, < 3.0.0 || >= 4.2.3"`
+
+The basic comparisons are:
+
+  - `=`: equal (aliased to no operator)
+  - `!=`: not equal
+  - `>`: greater than
+  - `<`: less than
+  - `>=`: greater than or equal to
+  - `<=`: less than or equal to
+
+# Hyphen Range Comparisons
+
+There are multiple methods to handle ranges and the first is hyphens ranges.
+These look like:
+
+  - `1.2 - 1.4.5` which is equivalent to `>= 1.2, <= 1.4.5`
+  - `2.3.4 - 4.5` which is equivalent to `>= 2.3.4 <= 4.5`
+
+# Wildcards In Comparisons
+
+The `x`, `X`, and `*` characters can be used as a wildcard character. This works
+for all comparison operators. When used on the `=` operator it falls
+back to the tilde operation. For example,
+
+  - `1.2.x` is equivalent to `>= 1.2.0 < 1.3.0`
+  - `>= 1.2.x` is equivalent to `>= 1.2.0`
+  - `<= 2.x` is equivalent to `<= 3`
+  - `*` is equivalent to `>= 0.0.0`
+
+Tilde Range Comparisons (Patch)
+
+The tilde (`~`) comparison operator is for patch level ranges when a minor
+version is specified and major level changes when the minor number is missing.
+For example,
+
+  - `~1.2.3` is equivalent to `>= 1.2.3 < 1.3.0`
+  - `~1` is equivalent to `>= 1, < 2`
+  - `~2.3` is equivalent to `>= 2.3 < 2.4`
+  - `~1.2.x` is equivalent to `>= 1.2.0 < 1.3.0`
+  - `~1.x` is equivalent to `>= 1 < 2`
+
+Caret Range Comparisons (Major)
+
+The caret (`^`) comparison operator is for major level changes once a stable
+(1.0.0) release has occurred. Prior to a 1.0.0 release the minor versions acts
+as the API stability level. This is useful when comparisons of API versions as a
+major change is API breaking. For example,
+
+  - `^1.2.3` is equivalent to `>= 1.2.3, < 2.0.0`
+  - `^1.2.x` is equivalent to `>= 1.2.0, < 2.0.0`
+  - `^2.3` is equivalent to `>= 2.3, < 3`
+  - `^2.x` is equivalent to `>= 2.0.0, < 3`
+  - `^0.2.3` is equivalent to `>=0.2.3 <0.3.0`
+  - `^0.2` is equivalent to `>=0.2.0 <0.3.0`
+  - `^0.0.3` is equivalent to `>=0.0.3 <0.0.4`
+  - `^0.0` is equivalent to `>=0.0.0 <0.1.0`
+  - `^0` is equivalent to `>=0.0.0 <1.0.0`
+
+# Validation
+
+In addition to testing a version against a constraint, a version can be validated
+against a constraint. When validation fails a slice of errors containing why a
+version didn't meet the constraint is returned. For example,
+
+	c, err := semver.NewConstraint("<= 1.2.3, >= 1.4")
+	if err != nil {
+	    // Handle constraint not being parseable.
+	}
+
+	v, _ := semver.NewVersion("1.3")
+	if err != nil {
+	    // Handle version not being parseable.
+	}
+
+	// Validate a version against a constraint.
+	a, msgs := c.Validate(v)
+	// a is false
+	for _, m := range msgs {
+	    fmt.Println(m)
+
+	    // Loops over the errors which would read
+	    // "1.3 is greater than 1.2.3"
+	    // "1.3 is less than 1.4"
+	}

-mkwinsyscall generates windows system call bodies
-
-It parses all files specified on command line containing function
-prototypes (like syscall_windows.go) and prints system call bodies
-to standard output.
-
-The prototypes are marked by lines beginning with "//sys" and read
-like func declarations if //sys is replaced by func, but:
-
-  - The parameter lists must give a name for each argument. This
-    includes return parameters.
-
-  - The parameter lists must give a type for each argument:
-    the (x, y, z int) shorthand is not allowed.
-
-  - If the return parameter is an error number, it must be named err.
-
-  - If go func name needs to be different from its winapi dll name,
-    the winapi name could be specified at the end, after "=" sign, like
-
-    //sys LoadLibrary(libname string) (handle uint32, err error) = LoadLibraryA
-
-  - Each function that returns err needs to supply a condition, that
-    return value of winapi will be tested against to detect failure.
-    This would set err to windows "last-error", otherwise it will be nil.
-    The value can be provided at end of //sys declaration, like
-
-    //sys LoadLibrary(libname string) (handle uint32, err error) [failretval==-1] = LoadLibraryA
-
-    and is [failretval==0] by default.
-
-  - If the function name ends in a "?", then the function not existing is non-
-    fatal, and an error will be returned instead of panicking.
-
-Usage:
-
-	mkwinsyscall [flags] [path ...]
-
-Flags
-
-	-output string
-	      Output file name (standard output if omitted).
-	-sort
-	      Sort DLL and function declarations (default true).
-	      Intended to help transition from  older versions of mkwinsyscall by making diffs
-	      easier to read and understand.
-	-systemdll
-	      Whether all DLLs should be loaded from the Windows system directory (default true).
-	-trace
-	      Generate print statement after every syscall.
-	-utf16
-	      Encode string arguments as UTF-16 for syscalls not ending in 'A' or 'W' (default true).
-	-winio
-	      Import this package ("github.com/Microsoft/go-winio").

+
+### Linting
+
+Code must pass a linting stage, which uses [`golangci-lint`][lint].
+Since `./test` is a separate Go module, the linter is run from both the root and the
+`test` directories. Additionally, the linter is run with `GOOS` set to both `windows` and
+`linux`.
+
+The linting settings are stored in [`.golangci.yaml`](./.golangci.yaml), and can be run
+automatically with VSCode by adding the following to your workspace or folder settings:
+
+```json
+    "go.lintTool": "golangci-lint",
+    "go.lintOnSave": "package",
+```
+
+Additional editor [integrations options are also available][lint-ide].
+
+Alternatively, `golangci-lint` can be [installed][lint-install] and run locally:
+
+```shell
+# use . or specify a path to only lint a package
+# to show all lint errors, use flags "--max-issues-per-linter=0 --max-same-issues=0"
+> golangci-lint run
+```
+
+To run across the entire repo for both `GOOS=windows` and `linux`:
+
+```powershell
+> foreach ( $goos in ('windows', 'linux') ) {
+    foreach ( $repo in ('.', 'test') ) {
+        pwsh -Command "cd $repo && go env -w GOOS=$goos && golangci-lint.exe run --verbose"
+    }
+}
+```
+
+### Go Generate
+
+The pipeline checks that auto-generated code, via `go generate`, are up to date.
+Similar to the [linting stage](#linting), `go generate` is run in both the root and test Go modules.
+
+This can be done via:
+
+```shell
+> go generate ./...
+> cd test && go generate ./...
+```
