# MODULE:   	Grass Documentation
# AUTHOR(S):	Original author unknown - probably CERL
# PURPOSE:  	o Creates all manpages in $(GISBASE)/man/man1
#   	    	  (Think to add grass programmer's manual pages in
#   	    	  $(GISBASE)/man/man3 and file format in $(GISBASE)/man/man5
#   	    	  later...) 
#		o Copies html tree (without the other files) in
#   	    	  $(GISBASE)/documents The manual in html format will be in
#   	    	  $(GISBASE)/documents/html (default in tcltkgrass) 
#		o The manual in postscript will be in
#		  $(GISBASE)/documents/postscript
#		o The manual in pdf will be in $(GISBASE)/documents/pdf
#
#		Usage:
#		default: html
#		ps:      gmake5 . postscript-docs
#		pdf:     gmake5 . pdf-docs
#                               ^-- current directory
