makerepropkg: allow specifying the package in pacman -S format
We now accept: 1) # nothing in which case we'll use the PKGBUILD to retrieve... 2) name, or repo/name in which case we'll use pacman to cache the package and retrieve... 3) a filename Signed-off-by: Eli Schwartz <eschwartz@archlinux.org>

|
|||
packages and will be treated as additional artifacts to compare during the
|
||||
verification step.
|
||||
|
||||
A valid target(s) for pacman -S can be specified instead, and makerepropkg will
|
||||
download it to the cache if needed. This is mostly useful to specify which
|
||||
repository to retrieve from. If no positional arguments are specified, the
|
||||
targets will be sourced from the PKGBUILD.
|
||||
|
||||
In either case, the package name will be converted to a filename from the
|
||||
cache, and makerepropkg will proceed as though this filename was initially
|
||||
specified.
|
||||
|
||||
This implements a verifier for pacman/libalpm packages in accordance with the
