- *
- * -n: don't touch ANY files!

- * -q: The user is to be queried before touching each

- * -t: touch only files ending with the list of suffices, each

- *
- * -s: print a summary of the error's categories.
- *
- * -v: after touching all files, overlay vi(1), ex(1) or ed(1)
- * on top of error, entered in the first file with
- * an error in it, with the appropriate editor
- * set up to use the "next" command to get the other
- * files containing errors.
- *
- * -p: (obsolete: for older versions of pi without bug
- * fix regarding printing out the name of the main file
- * with an error in it)
- * Take the following argument and use it as the name of
- * the pascal source file, suffix .p
- *
- * -E: show the errors in sorted order; intended for
- * debugging.
- *
- * -S: show the errors in unsorted order
- * (as they come from the error file)
- *
- * infile: The error messages come from this file.
