define Package/uhub/description
    uhub is a high performance peer-to-peer hub for the ADC network.
        Its low memory footprint allows it to handle several thousand users
        on high-end servers, or a small private hub on embedded hardware.

# Sqlite based user authentication.
#
# This plugin provides a Sqlite based authentication database for
# registered users.
# Use the uhub-passwd utility to create the database and add/remove users.
#
# Parameters:
# file: path/filename for database.
#
#plugin /usr/lib/uhub/mod_auth_sqlite.so "file=/etc/uhub/users.db"

# Topic commands.
# Note: "topic" == "hub description" (as configured in uhub.conf)
#
# !topic      - change the topic (op required)
# !showtopic  - show the topic
# !resettopic - reset the topic to the default (op required)
#
# This plugins takes no parameters.
plugin /usr/lib/uhub/mod_topic.so

# Log file writer
#
# Parameters:

# A simple example plugin
#plugin /usr/lib/uhub/mod_example.so

# A plugin sending a welcome message.

# rules: path/filenam for the rules file
#
# NOTE: The files MUST exist, however if you do not wish to provide one then these parameters can be omitted.
#
# The motd/rules files can do the following substitutions:
# %n - Nickname of the user who entered the hub or issued the command.
# %a - IP address of the user
# %c - The credentials of the user (guest, user, op, super, admin).
# %% - Becomes '%'
# %H - Hour 24-hour format (00-23) (Hub local time)
# %I - Hour 12-hour format (01-12) (Hub local time)
# %P - 'AM' or 'PM'
# %p - 'am' or 'pm'
# %M - Minutes (00-59) (Hub local time)
# %S - Seconds (00-60) (Hub local time)

# Load the chat history plugin.
#
# This plugin provides chat history when users are connecting, or
# when users invoke the !history command.
# The history command can optionally take a parameter to indicate how many lines of history is requested.
#
# Parameters:
# history_max:     the maximum number of messages to keep in history
# history_default: when !history is provided without arguments, then this default number of messages are returned.
# history_connect: the number of chat history messages to send when users connect (0 = do not send any history)
