# This is designed for building and running single-source-file ICU programs.
#
# You can always download the latest from http://source.icu-project.org/repos/icu/tools/trunk/scripts/icurun
# Or, as an unofficial link, http://bit.ly/icu-run
#
# In its simplest usage,  simply type:
#
#     icurun  yourprogram.c
#       (or .cpp if it is a C++ program)
#
#  The tool will compile and then run the program
#
#  FINDING ICU
#  To find ICU, the following search order is used by priority:
#
#  1)    "-i <path>" .. the <path> will be searched for either a direct path to icu-config,
#            or a directory containing it, or a directory containing '/bin' containing it.
#        In other words, if icu-config is  /opt/local/bin/icu-config, any of the following will work:
#                 -i /opt/local
#                 -i /opt/local/bin
#                 -i /opt/local/bin/icu-config
#
#         Additionally, /icu/source is a built ICU source directory, either of the following will work:
#
#                 -i /icu
#                 -i /icu/source
#
#         Also, if /build is an out-of-source build, this will work:
#
#                 -i /build
#
#  2)    If there is an executable ~/.icurunrc script, it can set the variable "ICU_CONFIG" to point
#        directly to the icu-config file.
#        An example ~/.icurunrc script  contains just this line:
#
#              ICU_CONFIG=/home/srl/E/II/bin/icu-config
#
#  3)    ICU_CONFIG can be set in the environment to point to icu-config  ( it's overridden by the .icurunrc script )
#
#  4)    if "icu-config" is on the PATH, it will be used.
#
#
#  RUNNING
#   Any additional arguments following the file will be passed to the application.
#
#  TODO
#   * should support pkg-config, which is preferred over icu-config, although icu-config makes this usage
#     easier
#
#   * need to test the $PATH and $ICU_CONFIG usage models
