Revision 1.76 - (hide annotations) (download) (as text)
Tue Aug 21 00:21:17 2001 UTC (18 years, 1 month ago) by ite
Branch: MAIN
Changes since 1.75: +10 -4 lines
File MIME type: text/x-chdr
Gettext phase 2:
* Replced dummy _() define with the real one and added language domain binding
  code.
* added gettext's related m4 macros to aclocal
* added misc/config.guess and misc/config.sub system detection scripts
* added the po subdirectory containing:
  - eggdrop.pot: the template translation file.
  - POTFILES.in: a list of the source files containing _("") macros
  - update.pl: a small perl script to generate eggdrop.pot from the sources
    and to update existing translation files (*.po)
  - ChangeLog: list of changes in that directory.
* added VERSION and VERSION_NUM (replacing EGG_VERSION and EGG_VERSION_NUM)
  defines for versioning information. The version (+patch excepted) now changes
  by just editing an entry in top of configure.in.
* removed EGG_VERSION_MAX and EGGDROP_VERSION_MIN C macros that wheren't used
  anywhere.
* Modified bootstrap script
* added and and modified .cvsignore files
