# Usage: sh build.sh [<optional switches>] [clean]
#
#   where the optional switches are:
#       -output <PROGRAM_OUTPUT>  - executable filename ("eclipse")
#       -os     <DEFAULT_OS>      - default Eclipse "-os" value
#       -arch   <DEFAULT_OS_ARCH> - default Eclipse "-arch" value
#       -ws     <DEFAULT_WS>      - default Eclipse "-ws" value
#       -java <JAVA_HOME>  - java install for jni headers
#
#   All other arguments are directly passed to the "make" program.
#   This script can also be invoked with the "clean" argument.
#
#   Examples:
#   sh build.sh clean
#   sh build.sh -java /usr/j2se OPTFLAG=-g PICFLAG=-fpic
