#!/bin/sh
#
# This is a TCL script that tries to sync the changes in a local
# Fossil checkout to another machine. The changes are gathered into
# a tarball, then sent via ssh to the remote and unpacked.
#
# Usage:
#
# co-rsync.tcl REMOTE
#
# Where REMOTE is the root of the remote repository into which changes
# are to be moved.
#
# Use Case:
#
# Sometimes while in the middle of an edit it is useful to transfer
# the incomplete changes to another machine for testing. This could
# be accomplished using scp, but doing it that was is tedious if many
# files in multiple directories have changed. This command does all
# the necessary transfer using a single command.
#
# A Tcl comment, whose contents don't matter \
exec tclsh "$0" "$@"
# Begin by changing directories to the root of the check-out.
#
