Configuring / Compiling / Installing
------------------------------------
will be enabled). To enable a plugin, install missing dependencies (see
section `Prerequisites' above) and rerun `configure'. If you specify the
`--enable-<plugin>' configure option, the script will fail if the depen-
- dencies for the specified plugin are not met. If you specify the
+ dencies for the specified plugin are not met. In that case you can force the
+ plugin to be built using the `--enable-<plugin>=force' configure option.
+ This will most likely fail though unless you're working in a very unusual
+ setup and you really know what you're doing. If you specify the
`--disable-<plugin>' configure option, the plugin will not be built. If you
specify the `--enable-all-plugins' or `--disable-all-plugins' configure
options, all plugins will be enabled or disabled respectively by default.
