- * name __main - process command line, open files, and call main()
- *
- * synopsis __main(line);
- * char *line; ptr to command line that caused execution
- *
- * description This function performs the standard pre-processing for
- * the main module of a C program. It accepts a command
- * line of the form
- *
- * pgmname arg1 arg2 ...
- *
- * and builds a list of pointers to each argument. The first
- * pointer is to the program name. For some environments, the
- * standard I/O files are also opened, using file names that
- * were set up by the OS interface module XCMAIN.
