    I have a few suggestions for this tool:

    - we could also list if a component had patches applied ( for example in
      https://lab.nexedi.com/nexedi/nxd-bom/blob/9273cfb92e1163e786397b7665c62d61830fbb9b/example/ors-bom.txt#L36
      slapos does not really install http://www.python.org/ftp/python/2.7.18/Python-2.7.18.tar.xz it also
      applies a series of patches
      ( https://lab.nexedi.com/nexedi/slapos/blob/035f3382a4d768ea9c702842f3c3c2a1c20d6a21/component/python-2.7/buildout.cfg#L40-45 ).

    - output a machine readable format such as bom.json

-> Make corresponding TODO notes.

Program nxd-bom is intended to help generating bill of material for a
software-release or slapos node.

Generation of the BOM for a software-release is already draftly
implemented. Generation of the BOM for slapos node is thought-out, but
not currently implemented.

In provided example/ors-bom.txt it could be seen how both parts should
look like. And nxd-bom documents in corresponding TODO section how
BOM(slapos-node) should be computed.

I originally used this draft script to build ors-bom.txt as requested by
a customer, and I no longer actively work on it. However I suggest we
incrementally improve it as needed and maybe also integrate it to be run
automatically in _all_ our builds, so that whenever an SR is built, the
BOM.txt is also built automatically for it.

An utility to help preparing bill of materials for Nexedi software.
