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