#   Makefile for Fortran example library, libfortex77.a.
#
#   This is a rudimentary Makefile that works well enough if you don't
#   have include files etc., leading to secondary and tertiary dependencies.
#   If you have such files in use, and you change an include file,
#   the best thing to do is 'make clean' and then rebuild the whole thing.
#
#   A more orthodox Makefile would make the library dependent on a collection
#   of object files or, even more tedious, list each member of the archive
#   file separately as a target.  Such a parctice seems like a good idea in
#   theory but it isn't always as portable as it might seem.

#   LIBSRC is a list of source files that make up the run-time library.
#
#   LIBRARY is the path to the run-time library we're building.
#
#   MAINS is a list of main programs we're compiling and linking with
#   the library.  Note they are assumed to be the root name for their
#   corresponding source file.
#
#   FC is the name of the Fortran compiler and should be filled in by
#   make(1) on your system.  If not, fill it in yourself :-).  FFLAGS
#   isn't always set by the system but is included on the compile line
#   in case it gets set on the command line.
#
#   DEBUG is a catch all set of compile time options.  Set it to '-ansi'
#   to see warnings w.r.t. what's not really Fortran 77 in the programs.

#   The FRC target is used to 'force' the execution of the recipes for
#   any targets that list FRC as a prerequisite.  That way, if someone
#   parks a file called 'clean' in the directory, clean will still be made.
