=head1 NAME

cl-sendfile.pl - push a file over scp, in parallel

=head1 SYNOPSIS

Send files to cluster nodes.   This also archives those files in the /root/files to make tracking changes to the cluster
from default installs easier.

 cl-sendfile.pl -a -l /etc/httpd/conf/httpd.conf
 cl-sendfile.pl -d -l /tmp/foo.conf -r /usr/local/etc/foo.conf

 cl-sendfile.pl [-l $LOCAL_FILE] [-r $REMOTE_FILE] [-h] [-v] [--incl <pattern>] [--excl <pattern>]
        -l: local file/directory to rsync - passed through unmodified to rsync
        -r: remote location for rsync to write to - also unmodified
        -x: stage the file as a normal user and relocate using sudo (requires sudo root/NOPASSWD)
        -v: verbose output
        -h: print this message
