now that chrome_elf is its own top-level dir, i think this should become
chrome_elf.gyp rather than a .gypi file only relevant within the context of
chrome.gyp. see, for example, net/net.gyp, base/base.gyp, content/content.gyp.

Should <(version_full) be an input here? What about <(version_py_path)?

[Cait (Slow), 2013/11/06 21:18:06]

For reference:
https://code.google.com/p/chromium/codesearch#chromium/src/chrome/version.gypi

version_py_path is the path to chrome/tools/build/version.py (the script that
we're passing the inputs to).
version_path is the path to chrome/VERSION which stores current version info
(version.py takes this file as input)
version_full is a string containing the current versionin
MAJOR.MINOR.BUILD.PATCH form (I only use it for the manifest name).

The 'inputs' section does seem a bit redundant though. It might be possible to
either just pass '<@(_inputs)' to version_py_path, or remove the 'inputs'
section altogether, and just pass in the variables -- I'll look into that.
