Significantly more complex factoids can be built by using $variables, command-substitution, command-piping, /code invocation, and more. Read on!
## Channel namespaces
Factoids added in one channel may be called/triggered in another channel or in private message, providing that the other channel doesn't already have a factoid of the same name (in which case that channel's factoid will be triggered).
Factoids may be added to a special channel named `global`. Factoids that are set in this channel will be accessible to any channels. Factoids that are set in a specific channel will override factoids of the same name that are set in the `global` channel or other channels.
For example, if there were factoid named `malloc` set in `##c` and in `global`, and you invoke it in `##c` then the `##c` version would be used. If the factoid were triggered in any other channel, then the `global` version would be invoked.
Now imagine `##c++` also has a `malloc` factoid. If you invoke it in `##c++` then its version of the factoid would be used instead of `##c`'s or `global`'s versions. If you invoke it in a channel that is not `##c++` or `##c` then the `global` version would be used.
However, if there is no `malloc` factoid in the `global` channel but there is one in `##c` and `##c++`, and you attempt to invoke it in any other channel then PBot will display a disambiguation message listing which channels it belongs to and instructing you to use the [`fact`](#fact) command to call the desired factoid.
## Special commands
### /say
If a factoid begins with `/say` then PBot will not use the `<factoid> is <description>` format when displaying the factoid. Instead, it will simply say only the `<description>`.

## add_nick
You can use the [`factset`](#factset) command to set a special [factoid metadata](#factoid-metadata) key named `add_nick` to prepend the nick of the caller to the output. This is mostly useful for modules.

To create a factoid, use the `factadd` command. This command can alternatively
