# obs-commit-version.sh: update CAF packages on OBS from Jenkins.
# This shell script is created for easy updating CAF binary packages located
# on OpenSUSE Build Service (OBS). It should be issued from the Jenkins after
# release has proven to be operating, like this:
#
#     $ make
#     $ make test
#     $ make doc                          <-- this is a necessary step!
#     $ obs-commit-version.sh --release   <-- for release build
#     -or-
#     $ obs-commit-version.sh --nightly   <-- for nightly build
#
# In brief, it performs the following steps:
# 
#  1. Determines current version from <caf/config.h> header. It's crucial to
#     have this version set correctly for script to operate properly.
#  2. If was run in '--nightly' mode, ask Git to describe current position on
#     the revision tree related to determined stable version.
#  3. Checks out OBS project using "osc" tool. It uses default credentials
#     specified in ~/.oscrc configuration file.
#  4. Puts new source tarball into OBS project.
#  5. Updates version in various spec files.
#  6. Commits changes files to trigger new OBS build.
