=head1 NAME

Lufs - Perl plug for lufs

=head1 DESCRIPTION

  The C code is a lufs module with an embedded perl interpreter.
  All filesystem calls are redirected to Lufs::C, which in turn gives them to your subclass.

  currently, these filesystems are included:

  Lufs::Local
  Lufs::Ram
  Lufs::Http
  Lufs::Svn
  Lufs::Mux
  Lufs::Rot13
  Lufs::Sql
  Lufs::NetHood

  lufsmount -o logfile=/tmp/perlfslog perlfs://Lufs.Local/ /mnt/foo
  lufsmount perlfs://Lufs.Ram/ /mnt/bar
  lufsmount perlfs://Lufs.Rot13/mnt/bar /mnt/baz
  lufsmount -o uri=svn://datamoeras.org/perlufs perlfs://Lufs::Svn/
  lufsmount -o uri=http://datamoeras.org perlfs://Lufs::Http/
  lufsd none /mnt/join -o 'fs=perlfs,host=Lufs.Mux,root=/,dirs=/mnt/box1;/mnt/box2;/mnt/box3'
  
  # or, if you have autofs:
  cd /mnt/perl/Lufs.Local/
  cd /mnt/svn/perlufs
