# Exit codes:
#	  0 - succesful
#	  1 - help displayed
#	  2 - no spec file name in cmdl parameters
#	  3 - spec file not stored in repo
#	  4 - some source, patch or icon files not stored in repo
#	  5 - package build failed
#	  6 - spec file with errors
#	  7 - wrong source in /etc/poldek.conf
#	  8 - Failed installing buildrequirements and subrequirements
#	  9 - Requested tag already exist
#	 10 - Refused to build fractional release
#	100 - Unknown error (should not happen)

# Notes (todo):
#	- builder -u fetches current version first (well that's okay, how you compare versions if you have no old spec?)
#	- when Icon: field is present, -5 and -a5 doesn't work
#	- builder -R skips installing BR if spec is not present before builder invocation (need to run builder twice)
