5# This exposes the Chrome version as GN variables for use in build files.
6#
7# PREFER NOT TO USE THESE. The GYP build uses this kind of thing extensively.
8# However, it is far better to write an action (or use the process_version
9# wrapper in build/util/version.gni) to generate a file at build-time with the
10# information you need. This allows better dependency checking and GN will
11# run faster.
12#
13# These values should only be used if you REALLY need to depend on them at
14# build-time, for example, in the computation of output file names.
15
16# Give version.py a pattern that will expand to a GN scope consisting of
17# all values we need at once.
