# Description:
#   this script is supposed to provide a way to edit files on a 
#   webdav server using vim. It uses java programs GetDavFile.class and 
#   PutDavFile.class to get and put the files, and it uses vim to 
#   actually edit the file
#
# Notes:
#
#   By using the junk.txt file as a temporary editing file, there is no
#   danger of wiping out an existing file on the local system which has 
#   the same name as the webdav resource being requested
#
# Examples:
#   vimdav.sh slide/files/documents/alexis_docs/programming/dns-info.xml
