# used as the name of the executable.
#
# Remaining parameters are named arguments. These include:
# MAIN_MODULE  The module of the main class to launch if different from the
#     current module
# MAIN_CLASS   The Java main class to launch
# JAVA_ARGS   Processed into a -DJAVA_ARGS C flag
# CFLAGS   Additional CFLAGS
# CFLAGS_windows   Additional CFLAGS_windows
# LIBS_unix   Additional LIBS_unix
# LIBS_windows   Additional LIBS_windows
# LDFLAGS_solaris Additional LDFLAGS_solaris
# RC_FLAGS   Additional RC_FLAGS
# MACOSX_SIGNED   On macosx, sign this binary
# WINDOWS_STATIC_LINK   On windows, link statically with C runtime and libjli.
# OPTIMIZATION   Override default optimization level (LOW)
# OUTPUT_DIR   Override default output directory
# VERSION_INFO_RESOURCE   Override default Windows resource file
# NO_JAVA_MS   Do not add -ms8m to JAVA_ARGS.
