# @BLURB: helper eclass for building Chromium package in src/platform2
# @DESCRIPTION:
# Packages in src/platform2 are in active development. We want builds to be
# incremental and fast. This centralized the logic needed for this.

# @ECLASS-VARIABLE: WANT_LIBCHROME
# @DESCRIPTION:
# Set to yes if the package needs libchrome.

# @ECLASS-VARIABLE: PLATFORM_SUBDIR
# @DESCRIPTION:
# Subdir in src/platform2 where the gyp file is located.

# @ECLASS-VARIABLE: PLATFORM_NATIVE_TEST
# @DESCRIPTION:
# If set to yes, run the test only for amd64 and x86.
