If a distfile changes its checksum for every download because it is packaged
|
||||
on the fly on the server, like e.g. snapshot tarballs from any of the
|
||||
`https://*.googlesource.com/` sites, the checksum of the `archive contents`
|
||||
can be specified by prepending a commercial at (@).
|
||||
For tarballs you can find the contents checksum by using the command
|
||||
`tar xf <tarball.ext> --to-stdout | sha256sum`.
|
||||
|
||||
- `wrksrc` The directory name where the package sources are extracted, by default
|
||||
set to `${pkgname}-${version}`.
