Revision 1.1 - (show annotations) (download)
Sat Feb 23 20:13:30 2008 UTC (17 years, 8 months ago) by jmc
Branch: MAIN
CVS Tags: HEAD 
- get new version from: http://packages.qa.debian.org/m/mpack.html
  (files: mpack_1.6.orig.tar.gz, mpack_1.6-4.diff.gz, mpack_1.6-4.dsc)
  and apply patch 'mpack_1.6-4.diff' to original dir: mpack_1.6/
- this fix the MD5 coding on 64.bit platforms (well, seems to).
- added in Contrib to allow separate test (since building mpack seems fishy)
