## vim:ft=zsh

## Distributed under the same BSD-ish license as zsh itself.
# If user-server is true in the :vcs_info:p4:... context, contact the
# server to decide whether the directory is handled by Perforce. This can
# cause a delay if the network times out, in particular if looking up the
# server name failed. Hence this is not the default. If a timeout
# occurred, the server:port pair is added to the associative array
# vcs_info_p4_dead_servers and the server is never contacted again. The
# array must be edited by hand to remove it.
#
# If user-server is false or not set, the function looks to see if there is
# a file $P4CONFIG somewhere above in the hierarchy. This is far from
# foolproof; in fact it relies on you using the particular working practice
# of having such files in all client root directories and nowhere above.
