HOWTO: Use re2c and compiled SpamAssassin rules

Hash: SHA1

This is intended as a brief guide to using the program "re2c" to 
generate compiled rules which speeds up SpamAssassin quite a bit.

Please can someone (who understands the wiki's text formatting system) 
upload this to the wiki for me!

1) Download the program "re2c" from 
"http://sourceforge.net/projects/re2c". If you are running an RPM-based 
system then download the .src.rpm file, else download the .tar.gz file.
2) Build "re2c".
2a) If you downloaded the .src.rpm file, then
       rpmbuild --rebuild re2c*.src.rpm
       cd /usr/src/redhat/RPMS/i386 (swap "redhat" for "packages" if 
that dir doesn't exist)
       rpm -Uvh re2c-0.12.0-1.i386.rpm (i.e. not the "debuginfo" version 
of the file)
2b) If you downloaded the .tar.gz file, then
       tar xzf re2c*tar*gz
       cd re2c*
       ./configure
       make
       make test
       make install
3) Compile the current set of SpamAssassin rules
       sa-compile
4) Tell SpamAssassin to use the compiled rules. Edit 
/etc/mail/spamassassin/v320.pre and uncomment the line
       loadplugin Mail::SpamAssassin::Plugin::Rule2XSBody
    by removing the "# " from the start of the line.
5) If you are using Rules-Du-Jour then tell it to recompile the rules 
after it downloads them. Edit the file /usr/bin/rules_du_jour and look 
for the line that contains
       SA_RESTART="
    Change this line to say
       SA_RESTART="sa-compile && /etc/init.d/spamassassin restart";
6) Restart MailScanner.

If you have any problems, let the mailing list know.
