# Do you ever got headache from reading Makefiles ? I will help you and
# me to understand this Makefile: 
# 
# The main file is doc.gpm (which is generated by configure from doc.gpm.in).
#
# doc.gpm is not 'real' texinfo, real texinfo is generated by infofilter
# to gpm.texinfo. 
#
# gpm.texinfo is the source of all other formats. 
#
# info is generated by makeinfo (I make that for you).
#
# man pages are generated with the help of manpager.
#
# dvi is generated from texinfo with a small block in this Makefile.
#
# ps is generated from dvi source.
#
