Eelco Dolstra d897fc5501 * Some prototype code to make dealing with options in Nixpkgs/NixOS 
easier.  Instead of writing

    config.get ["foo" "bar"]

  it would be much cleaner to just write

    config.foo.bar

  only this doesn't handle the case where option foo.bar is not
  supplied in the configuration; in that case we need to take the
  default value from some set of option definitions
  (system/options.nix in NixOS).

  Following a suggestion from Martin, the function `combine' (need
  better name) takes a set of option definitions (which follow the
  attribute set structure of the options) and a set of options and
  fills in missing values in the latter with default values from the
  former.  This only works with very recent versions of Nix (it needs
  Marc Weber's listToAttrs primop).

Michael Raskin 6d4fa01f1e Added strings-with-deps, a set of functions that are intended to 
build a minimal text which includes given strings and satisfies
'dependencies' of type A requires B to go before it. Just like
global variable intialization must occur before using them. Supposed
to be used for constructing builder.sh .

Marc Weber 8f3a8b5006 renamed chosenOptions to chooseOptionsByFlags and added support for optionals 
(thus you don't need to write flag definitions, passing a dependency or not is enough)

Michael Raskin efbabdb598 Converted Vim package to a template-based form with only lists filled in manually. Added library functions to support it. Added two proposed package templates to top-level, so that every discussion about package format can result in just editing templates or adding new ones.

Eelco Dolstra c5e1ae5eaf * Purity fix in building Python: don't let it search in /usr/include 
and /usr/lib to determine what optional modules (like bzip2, zlib,
  dl, etc.) to build.  Unfortunately there doesn't seem to be a way to
  tell the Python build process to look anywhere else, so I had to
  patch setup.py.
