@@ -173,6 +173,9 @@ The following modifications are made to makepkg:
* Timestamps in `$pkgdir` are reset to "1990-01-01 0:0:0 +0", so that
the resulting tarball will be the same, regardless of when it was
created.
+ * Sort the files included in the tarball; normally the order of files
+ in a tarball is essentially random (even if it tends to be the same
+ when re-created on the same machine).
* append `-libre` to `$srcdir`
* append `-libre` to `$pkgbasedir` (which becomes `$pkgdir`)
* Don't check if the package has already been built.
