"**         includes printf, fprintf, sprintf, vprintf, vfprintf, and\n"
"**         vsprintf.  This module adds the following:\n"
"**\n"
"**           *  snprintf -- Works like sprintf, but has an extra argument\n"
"**                          which is the size of the buffer written to.\n"
"**\n"
"**           *  mprintf --  Similar to sprintf.  Writes output to memory\n"
"**                          obtained from malloc.\n"
"**\n"
"**           *  xprintf --  Calls a function to dispose of output.\n"
"**\n"
"**           *  nprintf --  No output, but returns the number of characters\n"
"**                          that would have been output by printf.\n"
"**\n"
"**           *  A v- version (ex: vsnprintf) of every function is also\n"
"**              supplied.\n"
"**\n"
"**      +  A few extensions to the formatting notation are supported:\n"
"**\n"
"**           *  The \"=\" flag (similar to \"-\") causes the output to be\n"
"**              be centered in the appropriately sized field.\n"
"**\n"
"**           *  The %b field outputs an integer in binary notation.\n"
"**\n"
"**           *  The %c field now accepts a precision.  The character output\n"
"**              is repeated by the number of times the precision specifies.\n"
"**\n"
"**           *  The %' field works like %c, but takes as its character the\n"
"**              next character of the format string, instead of the next\n"
"**              argument.  For example,  printf(\"%.78'-\")  prints 78 minus\n"
"**              signs, the same as  printf(\"%.78c\",'-').\n"
"**\n"
"**      +  When compiled using GCC on a SPARC, this version of printf is\n"
"**         faster than the library printf for SUN OS 4.1.\n"
