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