22 hwloc-compress-dir takes an input directory containing XML exports and
23 tries to compress it by computing topology diffs between them (with the
24 hwloc-diff program). Each file is copied in the output directory ei‐
25 ther as a diff if it could be compressed, or as its original entire
26 file otherwise.
27
28 hwloc-compress-dir may recompress a directory that was previously com‐
29 pressed. All input files that are already in the output directory, ei‐
30 ther compressed or not, are ignored. New input files are compressed as
31 much as possible as usual.
32
33 For each file of the directory, the output filename is the same as the
34 original if not compressed, otherwise its extension is changed to
35 .diff.xml.
36
37 Compressed files are based on another non-compressed topology. Its
38 name is stored in the refname topology diff attribute.
39
40 The generated output diff files may be used with hwloc-patch just like
41 any file generated by hwloc-diff.
42
44 To compress the input files from directory in into directory out:
45
46 $ hwloc-compress-dir in out
47
49 Upon successful execution, hwloc-compress-dir returns 0.
50
51 hwloc-compress-dir will return nonzero if any kind of error occurs,
52 such as (but not limited to) failure to parse the command line.
