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