+$! ----- Soubroutines to actually build the shareable libraries
+$! The way things work, there's a main shareable library creator for each
+$! supported architecture, which is called from the main code above.
+$! 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
