# BE CAREFUL in editing:
#	due to the large number of index files, and my use of a non standard
#	info input file, any file $(TARGET).* is removed by "make clean"
#
#	I chose to use a prefix for the input file ("doc.$(TARGET)"), to ease
#	makeing clean and applying my own rules.

# First of all, retrieve features of makeinfo, to know if we can do images
# and --html. Also, allow MAKEINFO to be specified on the commandline to
# allow me testing with various versions.

# NOTE: it looks like semi-old versions can do images too, so CANDOIMAGES
#	is not (yet?) used


MAKEINFO = @MAKEINFO@
# According to whether this makeinfo can output html, autoconf define these

# These rules used to be expressed as "%.texinfo: doc.%" etc. However, this
# is gmake-specific, so I turned every % to $(TARGET), thus loosing generality
# but gaining portability. I also had to drop "$^": it worked with gmake
# and not pmake, while "$<" worked with pmake and not gmake.
# with gmake and not pmake.
