* -I: the following name, `ignorename' contains a list of

* Default: ~/.errorsrc
*
* -n: don't touch ANY files!
*
* -q: The user is to be queried before touching each
* file; if not specified, all files with hard, non
* ignorable errors are touched (assuming they can be).
*
* -t: touch only files ending with the list of suffixes, each
* suffix preceded by a dot.
* eg, -t .c.y.l
* will touch only files ending with .c, .y or .l
*
* -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.
* Default: stdin
