#  This script reports various configuration settings that may be needed
#  when using the MySQL client library.
#
#  This script try to match the shell script version as close as possible,
#  but in addition being compatible with ActiveState Perl on Windows.
#
#  All unrecognized arguments to this script are passed to mysqld.
#
#  NOTE: This script will only be used on Windows until solved how to
#        handle @LIBS@ and other strings inserted that might contain
#        several arguments, possibly with spaces in them.
#
#  NOTE: This script was deliberately written to be as close to the shell
#        script as possible, to make the maintenance of both in parallel
#        easier.
