NAME
Mail::SpamAssassin::Plugin::Rule2XSBody - speed up SpamAssassin by compiling regexps
SYNOPSIS
loadplugin Mail::SpamAssassin::Plugin::Rule2XSBody
DESCRIPTION
This plugin will use native-code object files representing the ruleset, in order to provide significant speedups in rule evaluation. Note that "sa-compile" must be run in advance, in order to compile the ruleset using "re2c" and the C compiler. See the "sa-compile" documentation for more details.
