# This is a TCL script that tries to sync the changes in a local |
|
4
|
# Fossil checkout to another machine. The changes are gathered into |
|
5
|
# a tarball, then sent via ssh to the remote and unpacked. |

# Usage: |

|

|
# co-rsync.tcl REMOTE |
|
10
|
# |
|
11
|
# Where REMOTE is the root of the remote repository into which changes |
|
12
|
# are to be moved. |
|

|
# Use Case: |
|
15
|
# |
|
16
|
# Sometimes while in the middle of an edit it is useful to transfer |
|
17
|
# the incomplete changes to another machine for testing. This could |
|
18
|
# be accomplished using scp, but doing it that was is tedious if many |
|
19
|
# files in multiple directories have changed. This command does all |
|
20
|
# the necessary transfer using a single command. |
|

# A Tcl comment, whose contents don't matter \ |
