$! ----- Soubroutines to build the shareable libraries
$! For each supported architecture, there's a main shareable library
$! creator, which is called from the main code above.
$! The creator will define a number of variables to tell the next levels of
$! subroutines what routines to use to write to the option files, call the
$! main processor, read_func_num, and when that is done, it will write version
$! data at the end of the .opt file, close it, and link the library.
$!
$! read_func_num reads through a .num file and calls the writer routine for
$! each line. It's also responsible for checking that order is properly kept
$! in the .num file, check that each line applies to VMS and the architecture,
$! and to fill in "holes" with dummy entries.
$!
$! The creator routines depend on the following variables:
$! libnum The name of the .num file to use as input
$! libolb The name of the object library to build from
$! libid The identification string of the shareable library
$! libopt The name of the .opt file to write
$! libtit The title of the assembler transfer vector file (VAX only)
$! libmar The name of the assembler transfer vector file (VAX only)
$! libmap The name of the map file to write
$! libgoal The name of the shareable library to write
$! libref The name of a shareable library to link in
$!
$! read_func_num depends on the following variables from the creator:
$! libwriter The name of the writer routine to call for each .num file line
