Viewing changes to src/Resize/resizedialog_impl.cpp

  • Committer: Bazaar Package Importer
  • Author(s): Cyril Brulebois
  • Date: 2008-01-06 04:39:36 UTC
  • mfrom: (1.1.1 upstream)
  • Revision ID: james.westby@ubuntu.com-20080106043936-a9u9g7yih3w16ru5
Tags: 1.9.0-1
* New upstream release.
* Replace “COPYING” with “LICENSE” in the NOT_NEEDED variable of
  debian/rules, following upstream's renaming.
* Update debian/links accordingly.
* Delete the matching TODO item since there's no longer needed to have a
  patched (with HTML tags) license file to get a correct display in the
  “License agreement” tab.
* Update the gcc4.3 patch (drop the hunk touching src/Libpfs/pfs.cpp):
   - 20_gcc4.3_includes.
* Add a link from /usr/share/qtpfsgui/html to the HTML documentation
  under /usr/share/doc/qtpfsgui/html since the former is used at runtime
  to display the manual.
