X * $Log:    rcsit.c,v $
X * Revision 1.20  87/05/04  21:50:53  src
X * added -F - flag. This option causes an additional header field for
X * inclusion of compile-time options into object-files to be inserted
X * into the C-source. The man-entry is also updated.
X *
X * Revision 1.19  86/06/12  20:29:43  src
X * The previous version was unable to look up templates in the
X * directory $TEMPLATES, when -t - option is absent but the
X * environment-variable TEMPLATES is set. Fixed that. If no -t - option
X * was given, but $TEMPLATES is non NULL, then -t is assumed and
X * $TEMPLATES is used as path to template-files.
X *
X * Revision 1.18  85/11/26  17:03:32  mcooper
X * Change message telling of what header was added.
X *
X * Revision 1.17  85/11/26  16:40:55  mcooper
X * Changed the default -t option to FALSE.
X * Added specifying directory to look for .template.*
X * files in via -tdirectory.
X *
X * Revision 1.16  85/11/11  21:35:34  mcooper
X * Added call to access() to see if the file
X * could be read.
X *
X * Revision 1.15  85/11/11  21:22:33  mcooper
X * Changed comment char for fortran files
X * from "*" to "c".  This is what RCS uses.
X *
X * Revision 1.14  85/11/11  20:08:43  mcooper
X * Added descriptions for fortran (.f) files.
X *
X * Revision 1.13  85/11/11  19:52:17  mcooper
X * Modified default header templates to not bother specifying
X * the RCS file name of the file.  co(1) worries about it.
X *
X * Revision 1.12  85/10/27  19:10:07  mcooper
X * Fixed bug that would not use template files if a file
X * type was forced with -c, -h, etc.
X *
X * Revision 1.11  85/10/27  18:48:27  mcooper
X * Extended template file.  You can now have template
X * files describing all the types of files that
X * rcsit "knows" about.  The file $HOME/.template.*
X * (where ``*'' is a ``.'' suffix rcsit can guess at or
X * the type of file that is specified with an override)
X * is checked for existance.  If not present, the default
X * header (built into rcsit) will be used.
X *
X * Revision 1.10  85/10/27  16:15:53  mcooper
X * Added printing of what rcsit is doing if tflag is
X * true.  Also added new headers.
X *
X * Revision 1.9  85/10/27  14:47:39  mcooper
X * Added new template feature.  If the file
X * .template exists in the users HOME directory,
X * then that file is used as the header file instead
X * of the defaults for each type of file.  This can
X * be disabled with the -t option in case the file
X * is say a shell script.  With the template feature
X * turned off, the auto guessing is re-inabled.
X * Also, rcsit now removes its temporary files.
X *
X * Revision 1.8  85/09/28  14:11:45  mcooper
X * Added feature: if the environment variable RCSDIR is
X * present, rcsit will attempt to make a symbolic
X * link to the directory when the -I flag is used.
X * This is done only when -I is specified AND the
X * directory RCS is not present.  You may disable this
X * feature with the -d option.  Note also that if RCSDIR
X * is not in the environment and the above conditions
X * are true, that a normal directory called RCS will
X * be created.
X *
X * Revision 1.7  85/09/19  15:59:53  mcooper
X * Kludge part 2 -- If you specify a ci -l of a
X * man file, then the header is messed up.
X * Fix: After initializing the comment string,
X * unlink the file and then run co -l.
X *
X * Revision 1.6  85/09/19  15:39:57  mcooper
X * Now knows about ``Manual'' type files.
X *
X * Revision 1.5  85/09/19  14:23:24  mcooper
X * Added lineprint() function to print things out
X * nicely.  Fixed bug for Manual type files.  Due
X * to the fact that RCS does not not the suffixes of
X * manuals, it therefor does not know what kind of
X * comment string to use.  Thus, I kludge by running
X * a ``rcs -c`... ' file'' to tell rcs the comment
X * string.
X *
X * Revision 1.4  85/09/19  13:28:22  mcooper
X * Fixed bug in auto_guess.  Would not continue through function
X * when file type was ``Makefile''.
X *
X * Revision 1.3  85/09/19  13:19:50  mcooper
X * Added ``Shell Script'' file type.
X *
X * Revision 1.2  85/09/19  10:08:36  mcooper
X * Added code to run RCS commands (rcs & ci) on files.
X * Fixed bug that limited number of command line files specified to
X * nine.  Several other minor fixes and improvements.
X *
X * Revision 1.1  85/09/17  11:33:33  mcooper
X * Initial revision
