HWLOC-COMPRESS-DIR(1)		     hwloc		 HWLOC-COMPRESS-DIR(1)

NAME
       hwloc-compress-dir - Compress a directory of XML	topologies

SYNOPSIS
       hwloc-compress-dir [options] <inputdir> <outputdir>

OPTIONS
       -R --reverse
	      Uncompress a previously compressed directory.

       -v --verbose
	      Display verbose messages.

DESCRIPTION
       hwloc-compress-dir  takes an input directory containing XML exports and
       tries to	compress it by computing topology diffs	between	them (with the
       hwloc-diff  program).   Each file is copied in the output directory ei-
       ther as a diff if it could be compressed, or  as	 its  original	entire
       file otherwise.

       hwloc-compress-dir  may recompress a directory that was previously com-
       pressed.	All input files	that are already in the	output directory,  ei-
       ther  compressed	or not,	are ignored. New input files are compressed as
       much as possible	as usual.

       For each	file of	the directory, the output filename is the same as  the
       original	 if  not  compressed,  otherwise  its  extension is changed to
       .diff.xml.

       Compressed files	are based on  another  non-compressed  topology.   Its
       name is stored in the refname topology diff attribute.

       The  generated output diff files	may be used with hwloc-patch just like
       any file	generated by hwloc-diff.

EXAMPLES
       To compress the input files from	directory in into directory out:

	   $ hwloc-compress-dir	in out

RETURN VALUE
       Upon successful execution, hwloc-compress-dir returns 0.

       hwloc-compress-dir will return nonzero if any  kind  of	error  occurs,
       such as (but not	limited	to) failure to parse the command line.
