MultiAddonManager

A MetaMod plugin that allows you to use multiple workshop addons at once and have clients download them.

Commands

mm_extra_addons <ids> The workshop IDs of extra addons separated by commas, addons will be downloaded (if not present) and mounted (e.g. "3090239773,3070231528"). Once downloads are done, the map is automatically reloaded so content can be precached.
mm_extra_addons_timeout <seconds> How long until clients are timed out in between connects for extra addons, timed out clients will reconnect for their current pending download.
mm_print_searchpaths Print all the search paths currently mounted by the server.
mm_download_addon <id> Download an addon manually.

Both of these commands require a map reload to apply changes.
mm_add_addon <id> Add an addon to the list, but don't mount.
mm_remove_addon <id> Remove an addon from the list, but don't unmount.
