	path_info_routines package - package version 1.2a.  18 Jul 99

Incompatibilities w/earlier versions:
	parse_path_info exits with status 250 instead of status 1 if
a problem is encountered.  Similarly, make_path_info_string exits with
statuses 250->253 instead of 1-4 in case of problems.  The original
behavior can be regained by compiling the appropriate program defining
ERROR_EXIT_STATUS as 1.

New features:
	parse_path_info and make_path_info_string accept a -nonewline
switch which suppresses the newline at the end of their output. -no
can be used as a synonym for -nonewline.
	make files support the idea of an include directory

New files:
	I think all files EXCEPT path_info_routines.c are new.  Although
path_info_routines.c depends on path_info_routines.h, it does not use
the changed parameters in that file, so things that depend only on
path_info_routines.c should not need rebuilding.



Installation notes for path_info package

	The package logically is in 2 pieces; path_info_routines.c (& .h),
and the executables make_path_info_string, parse_path_info, and
test_path_info.
	path_info_routines is used by defgb, so it may already be on
the system someplace.  Versions & locations should be checked before
proceeding.

        makefile.path_info assumes that path_info_routines.c
is found in LIBDIR (and path_info_routines.o will be built there).
It assumes that the main programs .c files are found in SRCDIR and that
their .o files are to be built there.  It assumes that path_info_routines.h
and error_exit_defn.h are found in INCDIR.  Finally, it assumes the executables
will be built in BINDIR.  It defaults all directories to .
	path_info_routines.c & .h and error_exit_defn.h should be moved to
their locations.  makefile.path_info's CC, CFLAGS, BINDIR, INCDIR,
LIBDIR & SRCDIR macros should be checked for suitability.  They can be edited,
or overridden on the command line that invokes the make file.
	Finally
		make -f makefile.path_info [macro1=value1 ...]
To build test_path_info,
		make -f makefile.path_info ./test_path_info [macro1=value1 ...]
(the ./ before test_path_info assumes SRCDIR has been defined as .  If not,
string should be SRCDIR/test_path_info, w/SRCDIR replaced by its defn)
