# Functions used to handle an --install-dir=<dir> option, this can be used
# to specify an installation path under <prebuilts>/
#
# Usage:
#
#  1) Call 'install_dir_register_option <name>' to register the option
#     and use '<prebuilts>/<name>' as the default location. If <name> is
#     empty, then '<prebuilts>/install' will be used as the default.
#
#  2) After parsing the options, and _after_ 'prebuilts_dir_parse_option',
#     call 'install_dir_parse_option'. This will define the INSTALL_DIR
#     global variable correspoinding to your installation directory.
#

# $1: installation sub-directory. Optional, default is 'install'
