Hi Cyril,

Great, thank you!

Quick notes:

* Implementing help under -h would be a bonus (it segfaults on -h, metadata.c
  has it). But this should not block you merging it.

* Please merge with whitespace error
$ make check-metaparse-sh 
CHECK metadata/metaparse-sh.c
metaparse-sh.c:90: ERROR: code indent should use tabs where possible

* Resulting JSON has true, 1 instead would be nice. Again, tiny detail.
