## .texi files are generated files, not primary sources, and should not 
## be distributed.  Automake, however, does not create rules to generate
## pdf and html documentation unless the info and texi files will be
## distributed.  Various hacks, including using the nodist_ prefix and 
## DISTCLEANFILES, do not work.  The current solution is to build the texi
## files and create the correct Makefile rules and then use the dist-hook
## feature to remove the .texi files from the distribution just before it 
## is archived in a tar file.
dist-hook:
	( cd $(distdir) ; rm -f $(octave_TEXINFOS) ; )
