Signed-off-by: Samuel Martin <s.martin49@gmail.com>

---
Changes since v4:

* update the readme according to the kconfiglib author's wishes

Script generating the target and host package tables, and the deprecated

Config.in files.

Changes since v5:
* fix shebang (Yann)
* generate files in $(O) (Thomas P.)
* minor fixes

Changes since v4:
* remove date in the generated lists

Chagnes since v3:
* Re-introduce try/except on the kconfiglib import. This is mandatory
  because the kconfiglib module is no longer embedded in the Buildroot
  source tree because of undefined license (the author wants to keep
  the authorship of his work of course, but he does not seem inclined
  to define any license on his project which would allow 3rd parties
  to re-use this project without any legal issues).

Changes since v1:
* many improvements, fixes, refactoring and cleanup (Arnout)
manual: cleanup appendix.txt

Changes since v5:
* s/stuff/features/ (Thomas P.)

Changes since v1:
* move the surrounding text of the list back in appendix.txt (Arnout)

The generated lists are automatically updated when building the manual.

Changes since v5:
* Generate lists in $(O)

Changes since v4:
* systematically update the generated lists when building the manual

Changes since v2:
* remove PYTHONPATH stuff since the kconfiglib module is next to
  gen-manual-lists.py (Arnout)

Changes since v1:
* add manual-update-lists target to the .PHONY one (Arnout)
* misc. fixes/updates
update gitignore

Do not track *.pyc files (from modules embedded in Buildroot source
tree).

manual: do not track generated files

Since there is no need to edit the generated list, we don't need
to keep the files under git control, so remove the existing lists.
