# TODO
# - really long sourceX make preamble sorting totally fcked up (try snake.spec r1.1)
# - parse ../PLD-doc/BuildRequires.txt and setup proper BR epoches?
# - add "-nc" option to skip CVS interaction
# - sort Summary(XX)
# - sort Requires, BuildRequires
# - check if %description (lang=C) contains 8bit
# - desc wrapping is totally fucked up on global.spec,1.25, dosemu.spec,1.115-
