43 * mkstr - create a string error message file by massaging C source
45 * Bill Joy UCB August 1977
47 * Modified March 1978 to hash old messages to be able to recompile
48 * without addding messages to the message file (usually)
50 * Based on an earlier program conceived by Bill Joy and Chuck Haley
52 * Program to create a string error message file
53 * from a group of C programs. Arguments are the name
54 * of the file where the strings are to be placed, the
55 * prefix of the new files where the processed source text
56 * is to be placed, and the files to be processed.
58 * The program looks for 'error("' in the source stream.
59 * Whenever it finds this, the following characters from the '"'
60 * to a '"' are replaced by 'seekpt' where seekpt is a
61 * pointer into the error message file.
62 * If the '(' is not immediately followed by a '"' no change occurs.
64 * The optional '-' causes strings to be added at the end of the
65 * existing error message file for recompilation of single routines.
