# This stript is useful to prepare the tomboy-ng source tree to make an
# Debian Source Package

# If you submit it to Debian Mentors and get an error, or a revision of the packaging
# is requested, DO NOT DELETE THE WORKING Build* DIR, you need it to generate 
# fixes (run prepare.debian again, this time without the -n. Totally different 
# behaviour !

# Fine to blow it away if its not been uploaded with dput ! 

# Possibly fine to blow it away if it has not migrated from Mentors to unstable.
# But that needs clarification.

# For detailed instructions including ready to copy command lines see-
# https://github.com/tomboy-notes/tomboy-ng/blob/master/prepare.md


# 
# David Bannon, Jan 2021
# History -
#	2020-09-02 Added -D distro switch
#       2020-12-17 Restructed the multi control system to make it clearer.
#       2020-12-29 Split script into seperate Debian one, only Qt5.
#       2021-01-27 More detailed instructions on use.
#	2021-02-03 Include enough of first changelog to keep lintian off my back
#	2021-06-19 Made swichable between GTK2 and Qt5
#		   Moved Howto docs to github
#   2022-11-17 Now two seperate behavious, with -n, "new release" we download a new
#              set of files and generate a new .orig.tar.gz that must be uploaded.
#              Secondly, without the -n, we assume we are using an existing .orig.
#              and just repackaging. The Package version number is manually incremented and
#              the src dir renamed. Most of the code is skipped.
#   2022-11-30 Don't try to imcrement pack numb, must be done manually.
