zsh/Completion/compdump

# This is a function to dump the definitions for new-style
# completion defined by 'compinit' in the same directory.  The output
# should be directed into the "compinit.dump" in the same directory as
# compinit. If you rename init, just stick .dump onto the end of whatever
# you have called it and put it in the same directory.  This is handled
# automatically if you invoke compinit with the option -d.
#
# You will need to update the dump every time you add a new completion.
# To do this, simply remove the .dump file, start a new shell, and
# create the .dump file as before.  Again, compinit -d handles this
# automatically.

# Print the number of files used for completion. This is used in compinit
# to see if auto-dump should re-dump the dump-file.
