# 'make info' produces info files, as does 'make texinfo'
# 'make dv' produces dvi files (and lots of crap)
# 'make dvi' produces dvi files and lots of crap, then erases the crap
# 'make all' produces both info and dvi files, and cleans up afterwards
# 'make install' copies the info files to /usr/local/info (or the value
#     of INFODIR, if you change it)
# 'make html' produces html files (but requires a perl script: texi2html)
#     to get html files, change the next variable to point to the perl
#     script texi2html.  Also, if you run this by typing 'perl texi2html',
#     then the variable PERL should be set to perl.  If you run it by
#     typing 'texi2html', then the variable PERL should be set to nothing:
#     PERL=
#  
TEXI2HTML=texi2html
PERL=perl
#
TEXI2DVI=texi2dvi
MAKEINFO=makeinfo
