· About the changelog entries: Please do not just mention which files
you touched (that can be seen in the diff), but describe a bit what
(and why) you changed something. Especially group things you write
by "changes", not by file names:
* Do not link with Xext: we do not use it.
- Remove libxext-dev from Build-Depends.
- New patch: 06_Imakefile.diff
is more informative than
* debian/control
+ Removed libxext-dev in B-D, it's not necessary
* debian/patches/06_Imakefile.diff
+ Added, to fix dpkg-shlibdeps: warning
where other people have to find the connection themselves.
(Same for the switch from override_* targets to files in debian/.)
