Usage: ${0##*/} PKGBUILD
|
|
|
|
Convert an Arch Linux PKGBUILD to a universal standalone bash script. (The
|
|
infamous 'bash' is assumed because PKGBUILD are bash scripts.) The resulting
|
|
script tries to resemble makepkg build process where it makes sense. There is no
|
|
dependency resolution because we cannot guess the package names of the target
|
|
system.
|
|
|
|
Differences with makepkg
|
|
* Parameters are not the same.
|
|
* The output may differ.
|
|
* The fakeroot environment lies directly in \$pkgdir, not in \$pkgdir/\$pkgname.
