# DO NOT IMPORT THIS .gni FILE DIRECTLY! Use "$dir_pw_build/defaults.gni"!
#
# When these variables were originally created, Pigweed did not have a widely
# adopted naming pattern for build arguments declared by GN. For backwards
# compatibility, these arguments will retain their naming.
#
# Unfortunately, there's two problems with this:
#
#   1. It's not clear these variables come from Pigweed since they don't follow
#      the established naming patterns.
#   2. The names conflict with the attributes of pw_* wrapped targets, which
#      means you'll get confusing behavior if this declare_args() block gets
#      imported into the context of a regular build file. That is why this
#      .gni file is imported into a scope rather than handled like a regular
#      import. It truly is an amusing workaround, but it works.
#
# While it's possible to migrate away from these names, it's unlikely that will
# ever happen.
