NAME
       acpl - compile a	target architectures

SYNOPSIS
       acpl [options] [itfile] [otfile]

DESCRIPTION
       The  acpl  program compiles a decomposition-defined target architecture
       file itfile of type 'deco 0' into a compiled decomposition-defined tar-
       get 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 files.

OPTIONS
       -h     Display some help.

       -V     Display program version and copyright.

EXAMPLE
       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	archi-
       tecture description produced by amk_ccc(1) is read  from	 the  standard
       input, through the pipe.

	   $ amk_ccc 4 | acpl -	ccc4c.tgt.gz
