Not having access to rsync with the main Crosswire site, to avoid
fragmentation between the main site, and the mirror I emulated rsync via
FTP using the following in a cron job (which was as close as I could get):

/usr/bin/wget -nH -np -m --passive-ftp --user=anonymous --password=
mirror at user.com ftp://ftp.crosswire.org/pub/sword/raw

When something at the main site changed, it was replicated at the mirror,
if nothing changed, nothing was copies.  Nothing that existed on the mirror
differed from what was on the main sites (so the purpose was to have an
exact copy).

I provide this only to fill in technical details of how I was 'mirroring'
the main site, not to support some particular position or another.
