/* Copyright (c) 1989 by Daniel R. Zemke -- CompuServe [73230,1543] */
/* */
/* Purpose: Creates one or more libraries from all "*.c" files */
/* in the current directory. */
/* */
/* Example: Executing buildlib mylib scl */
/* */
/* Creates: mylibS.lib, mylibC.lib AND mylibL.lib */
/* (i.e. small, compact and large library versions of MYLIB) */
/* */
/* Parameters: Two and only two parameters are required. The first is */
/* used to specify the common name prefix for the series */
/* of generated libraries. The second parameter is a char */
/* string of one or more characters indicating desired */
/* memory models. Each library name is formed by suffixing */
/* the library series name with a character from the memory */
/* model list. The memory model list consists of */
/* contiguous characters without any surrounding quotes. */
/* Valid characters for the memory model list are : */
/* t s m c l h */
/* */
/* Assumptions: Turbo C for compile of source and DOS 2+ for execution. */
/* TCC and TLIB are in the current search path. */
/* Every "*.c" file in the current directory is to be */
/* included in target lib(s). */
/* Adequate memory to invoke tcc from within BUILDLIB */
/* using the system() call. */
