#
# This script is used to build libraries required by OpenZone for some platforms. Currently it
# builds all required libraries for NaCl and Android configurations that are not provided by SDKs.
# The following commands may be given (`build` is assumed if none):
#
# - `clean`: Delete everything in `ports` directory except downloaded sources.
# - `buildclean`: Delete build directories. Downloaded sources and installed libraries are left
#   intact.
# - `fetch`: Download sources into `ports/archives` directory.
# - `build`: Builds all libraries for all platforms.
