#
# Script to convert all ACE cast macro calls (e.g.
# ACE_static_cast (foo, bar)) to their standard C++ counterparts (e.g.
# static_cast<foo> (bar)).
#
# Use this script at your own risk. It appears to work correctly for
# most cases, but verify the results "just in case".
#
# @note Wildcards may be supplied as the "FILE" arguments to this
# script since the shell should expand the wildcards before
# executing the script.
#
# @bug The sed program used in this script may loop indefinitely on
# ACE casts with arguments split across multiple lines
# containing patterns it doesn't recognize.
