# Synopsys
# This script is used to build new Greyhole versions. It will:
#   1. Create a source TGZ, and RPM & DEB packages
#   2. Upload the new files on the greyhole.net host
#   3. Update the APT & YUM repositories (manual intervention required)
#   4. Install the new version locally (using apt-get or yum, depending on what's available)
#	5. Tag the git branch
#   6. Update the CHANGELOG on http://www.greyhole.net/releases/CHANGELOG
#   7. Send 'New version available' notifications by email, Twitter (@GreyholeApp), Facebook (Greyhole) and IRC (#greyhole on Freenode).
