+ * 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.
