Attached are two patch files for the abc2ps.c and buffer.c files in version
2.11.3 of abcm2ps. I am typesetting some choral music and needed more
flexible page number positioning. The patches expand the command line page
numbering argument.
I have defined five different page numbering modes:
0 page numbers off
1 page numbers always at top left
2 page numbers always at top right
3 page numbers at top left on even pages, top right on odd pages
4 page numbers at top right on even pages, top left on odd pages
then I expanded the '-N' command line option to set the mode with a
numerical argument. For instance,
abcm2ps -N 3 ooga.abc -O ooga.ps
I sent this patch to Jean-Fran�ois about two weeks ago and haven't heard
anything whether he might consider it for a future version, so I thought
I'd just post it here for anyone who might need such page numbering in the
short term. Actually I had originally patched version 3.0.17, but found
that the later version lacked some useful decorations, like !mp!, and so
went back to using 2.11.3.
