// theory of operation:
//  1. Build a complete set of applications
//  2. apply "nm" to each of the .o files that make up the libraries to subset
//     filter the results into two files for each, one with exported names, the
//     other with imported names.
//  3. apply "nm" to all of the elements which use ace & tao. build a list of
//     imported names 
//  4. Repeat the following steps until no entries remain in the list of 
//     imports
//  4.1 Take a name from the list of imports, locate the module containing the 
//      export of that name
//  4.2 Add the exporting module to the list of required modules, add its list
//      of exports to the list of resolved exports, add its imported names to
//      the list of imports.
//  4.4 Traverse the list of imported names to eliminate any found in the list
//      of exported names. 
//  4.5 go to step 4.1
//  5. construct a new makefile for all required modules.
//
//  Currently works only with GNU nm
