32 | * | |
ad33082a BJ |
33 | * -I: the following name, `ignorename' contains a list of |
34 | * function names that are not to be treated as hard errors. | |
35 | * Default: ~/.errorsrc | |
36 | * | |
37 | * -n: don't touch ANY files! | |
38 | * | |
39 | * -q: The user is to be queried before touching each | |
40 | * file; if not specified, all files with hard, non | |
41 | * ignorable errors are touched (assuming they can be). | |
42 | * | |
43 | * -t: touch only files ending with the list of suffices, each | |
44 | * suffix preceded by a dot. | |
45 | * eg, -t .c.y.l | |
46 | * will touch only files ending with .c, .y or .l | |
47 | * | |
48 | * -s: print a summary of the error's categories. | |
49 | * | |
50 | * -v: after touching all files, overlay vi(1), ex(1) or ed(1) | |
51 | * on top of error, entered in the first file with | |
52 | * an error in it, with the appropriate editor | |
53 | * set up to use the "next" command to get the other | |
54 | * files containing errors. | |
55 | * | |
56 | * -p: (obsolete: for older versions of pi without bug | |
57 | * fix regarding printing out the name of the main file | |
58 | * with an error in it) | |
59 | * Take the following argument and use it as the name of | |
60 | * the pascal source file, suffix .p | |
61 | * | |
62 | * -E: show the errors in sorted order; intended for | |
63 | * debugging. | |
64 | * | |
65 | * -S: show the errors in unsorted order | |
66 | * (as they come from the error file) | |
67 | * | |
68 | * infile: The error messages come from this file. | |
69 | * Default: stdin | |
