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

61 | * Default: ~/.errorsrc | |
62 | * | |
63 | * -n: don't touch ANY files! | |
64 | * | |
65 | * -q: The user is to be queried before touching each | |
66 | * file; if not specified, all files with hard, non | |
67 | * ignorable errors are touched (assuming they can be). | |
68 | * | |
69 | * -t: touch only files ending with the list of suffices, each | |
70 | * suffix preceded by a dot. | |
71 | * eg, -t .c.y.l | |
72 | * will touch only files ending with .c, .y or .l | |
73 | * | |
74 | * -s: print a summary of the error's categories. | |
75 | * | |
76 | * -v: after touching all files, overlay vi(1), ex(1) or ed(1) | |
77 | * on top of error, entered in the first file with | |
78 | * an error in it, with the appropriate editor | |
79 | * set up to use the "next" command to get the other | |
80 | * files containing errors. | |
81 | * | |
82 | * -p: (obsolete: for older versions of pi without bug | |
83 | * fix regarding printing out the name of the main file | |
84 | * with an error in it) | |
85 | * Take the following argument and use it as the name of | |
86 | * the pascal source file, suffix .p | |
87 | * | |
88 | * -E: show the errors in sorted order; intended for | |
89 | * debugging. | |
90 | * | |
91 | * -S: show the errors in unsorted order | |
92 | * (as they come from the error file) | |
93 | * | |
94 | * infile: The error messages come from this file. | |
95 | * Default: stdin | |
