source: trunk/debathena/scripts/install-sh @ 22720

Revision 22720, 12.9 KB checked in by ghudson, 14 years ago (diff)
Create an autoconfiscation transform step for Athena source trees before the orig archive is created. * debathena/scripts/mkinstalldirs, debathena/scripts/install-sh: Copies from automake 1.10 so that we aren't dependent on a specific version of automake. * debathena/scripts/aclocal.m4: The Athena aclocal.m4, resurrected from the attic. * debathena/scripts/daconfiscate: New script to copy in boilerplate and generate configure for Athena source directories. * debathena/scripts/dasource: Invoke daconfiscate for athena packages. Also, avoid creating conflicting orig archives by (1) leaving alone an existing orig archive and (2) searching the apt repositories for an orig archive before generating one.
