# 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-
# - it should change: /%source([0-9]+)/i to %{SOURCE\1}
# - extra quote on LDFLAGS line: https://bugs.launchpad.net/pld-linux/+bug/385836
# - %{with_foo:%attr()...} gets converted to %attr() %{with_foo:...} [vlc.spec]
# - 'R: foo ' (with traliling space) gets coverted to "R: foo\nR: " [vlc.spec @ 1.199 ]
