#	  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/bugs):
# - 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)
# - does not respect NoSource: X, and tries to cvs up such files [ example: VirtualBox-bin.spec and its Source0 ]
# TODO:
# - ability to do ./builder -bb foo.spec foo2.spec foo3.spec
# - funny bug, if source-md5 is set then builder will download from distfiles even if there is no url present:
#   Source10:	forwardfix.pl
#   # Source10-md5:	8bf85f7368933a4e0cb4f875bac28733
