copyrite - copyright utility


       copyrite [options] files...


       Copyrite  selectively  comments  source-files  to  prepend  a copyright


       Copyrite reads each file, and checks to ensure that they

       -      are nonbinary,

       -      contain either an SCCS or RCS identifier, and

       -      contain no prior copyright notice.

       The restriction to files containing SCCS or RCS identifiers is made  to
       avoid  modifying files that are used as references for test cases.  You
       may override this restriction with the "-f" option.   Copyrite  assumes
       SCCS  identifiers  are  constructed with "%W" or "%A" (and so yield the
       string "@(#)", followed by the  filename).   RCS  identifiers  "Id"  or
       "Header"  yield  the filename as well.  By looking for both the form of
       the identifier as well as matching the filename,  copyrite  can  reduce
       the  change  of  accidentally  changing  a  file  which is derived from
       another (e.g., via editing).

       Prior copyright notices are recognized by searching (ignoring case) for
       the  word  "copyright", followed by an (optionally comma-separated list
       of) years.

       If no conflict is found, copyrite then attempts to determine  the  type
       of  file  by  examining  its  name  and  contents.   If  successful, it
       completes the change by renaming its working file onto the input file.


       -c     directs copyrite to insert  the  string  "(c)"  after  the  word
              "Copyright"  in the generated notice.  Use of this option is not
              necessary, and may indeed result in a defective  (non-statutory)
              notice; however it is provided for cultural reasons.

       -e FILE
              redirects the standard error to the specified file.

       -f     forces  copyrite  to  markup  files  which  have  no RCS or SCCS

       -F     forces copyrite to modify files  which  have  notices  owned  by
              other organizations.

       -l LANG
              specify the default language for unknown cases (none)

       -L     directs  copyrite  to  operate on symbolic links that resolve to
              files or directories.  Normally these are ignored.

       -m FILE
              specifies a file  containing  text  for  owner  and  disclaimer.
              Copyrite  interprets  the  first  line of the file as the owner.
              The remainder of the file is formatted into a paragraph  as  the

       -o FILE
              redirects the standard output to the specified file.

       -n     shows  the  effect  of  changing  the  specified  files  without
              actually doing the change.  Copyrite writes  the  changes  to  a
              temporary file and computes the differences.

       -q     (quiet) suppress informational messages

       -r     removes  an existing notice (whose owner matches that specified,
              e.g., by the "-m" option).

       -R     recur into directories

       -s     strips comments which appear starting at the point in the  input
              files at which copyrite would insert a notice.

       -T     touches  the changed files with the current date.  If you do not
              use this  option,  copyrite  derives  the  year  from  the  last
              modification-date of the original file.

       -v     (verbose)

       -w NUMBER
              sets  the  width  of  the notice-comment The default width is 80


       Copyrite runs in either a UNIX or VAX/VMS environment.


       Copyrite consists of a single binary  file  (on  UNIX,  "copyrite",  on
       VAX/VMS, "copyrite.exe").


       Copyrite  can  process only 7-bit ASCII files, since it uses the eighth
       bit for intermediate masking of the regions where it can edit files.


       Make this able to operate on lists of years.
