#
#  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.
