What is ZNC-Extra?
ZNC-Extra is a package of some additional modules which are, for some reason, not enabled by default.
For version 1.0 and newer
There're no extra modules. Every module, which is shipped with ZNC, is compiled by default, with the exceptions of modules, which need additional dependencies.
For version between 0.076 and 0.206
Since 0.076, the extra modules are shipped with ZNC and can be enabled by passing
--enable-extra to configure during installation.
Read the ZNC installation instructions for details on how to install ZNC. Remember, pass
--enable-extra to configure (and additionally
--enable-tcl for modtcl) to include the whole extra package.
Read Compiling modules if you want to know how to compile single modules.
See the FAQ page if you encounter problems.
For version 0.074 and older
The extra modules were shipped in a separate download. Read about it here.
