# This script copies modified files from a source CVS tree to a destination
|
||
# tree. Modified files are detected by comparing their modification dates
|
||
# with the CVS Entries file.
|
||
#
|
||
# Modified files are copied in their entirety to the destination tree
|
||
# (no diffing is done). Files are only copied of the CVS version of the
|
||
# file is the same in both trees. If the destination file is modified
|
||
# already, it is backed up and replaced.
|
||
#
|
||
# To use this on your tree/platform, do the following:
|
||
#
|
||
# 1. Fix the !perl line, if necessary.
|
||
# 2. Fix $dirsep to be the directory separator on your platform.
|
||
# 3. Uncomment the appropriate $dst_linebreaks file specify what linebreaks
|
||
# you want for the copied files. This variable defines the *destination* linebreaks
|
||
# that you want your changes to be converted to.
|
||
# For example, if you have a linux volume
|
||
# mounted (via SAMBA perhaps) to your windows box where you've made changes to
|
||
# source files, you'd want $dst_linebreaks to be set for unix. This ensures that
|
||
# linebreaks are converted to the appropriate OS linebreak scheme for your *target* tree.
|
||
# 4. Set $src_tree and $dest_tree to point to the directories you want
|
||
# to sync up. These don't have to point to the root of the tree,
|
||
# but should be equivalent directories in the two trees.
