# PURPOSE
|
||
|
|
#
|
||
|
|
# This script uses a local directory to maintain a "mirror" of the curl
|
||
|
|
# packages listed in the remote curl web sites package list. Files present in
|
||
|
|
# the local directory that aren't present in the remote list will be removed.
|
||
|
|
# Files that are present in the remote list but not in the local directory
|
||
|
|
# will be downloaded and put there. Files present at both places will not
|
||
|
|
# be touched.
|
||
|
|
#
|
||
|
|
# WARNING: don't put other files in the mirror directory, they will be removed
|
||
|
|
# when this script runs if they don't exist in the remote package list!
|
||
|
|
#
|
||
|
|
|

# this is the directory to keep all the mirrored curl files in:
