More fun with GNU make

[mdlbear]

Finally got sufficiently disgusted with the fact that my website has my songs are indexed alphabetically by filename instead of by title, and fixed it.

The magic makefile lines are:

ZSONGS := $(shell perl -n -e '/file\{(.+\.flk)/ && print "$$1\n"' zongbook.tex)
SONGS = $(filter-out $(EXCLUDE), $(ZSONGS)) 

This assumes that zongbook.tex contains lines like:

\file{oldtime.flk}	% Old Time Computing 

.. and of course it does: it's the LaTeX file that generates my typeset songbook index.
