       acpl - compile a target architectures


       acpl [options] [itfile] [otfile]


       The  acpl program compiles a decomposition-defined target architecture file itfile of type
       'deco 0' into a compiled decomposition-defined  target  architecture  of  type  'deco  1',
       stored in file otfile.

       Compiling a decomposition-defined architecture amounts to computing the distance matrix of
       all possible subdomains, from the distance matrix of all terminal subdomains  provided  in
       the 'deco 0' format.  Since this computation is internally performed every time a 'deco 0'
       format is read, and is quadratic in time, pre-compiling the target architecture  by  means
       of  acpl  can  save some time when repeatedly computing mappings on a large decomposition-
       defined 'deco 0' target architecture.

       When the proper libraries have been included at compile time,  acpl  can  directly  handle
       compressed files, both as input and output. A stream is treated as compressed whenever its
       name is postfixed with a compressed file extension, such as in 'brol.tgt.bz2'  or  '-.gz'.
       The  compression  formats  which  can be supported are the bzip2 format ('.bz2'), the gzip
       format ('.gz'), and the lzma format ('.lzma', on input only).

       Since decomposition-defined target architecture files have a size which  is  quadratic  in
       the number of target vertices, because of the distance matrix structures, using compressed
       files to store them may save a lot of space, especially for compiled  target  architecture

       Create  a  compiled  cube-connected-cycle  target architecture of dimension 4, and save it
       under the gzip(1) format to file 'ccc4c.tgt.gz'. The dash '-' standard file name  is  used
       so  that  the 'deco 0' target architecture description produced by amk_ccc(1) is read from
       the standard input, through the pipe.

           $ amk_ccc 4 | acpl - ccc4c.tgt.gz
