If your package needs to install GNU info files, they should be listed in the INFO variable (without the trailing .info), one entry per document. These files are assumed to be installed to PREFIX/INFO_PATH. You can change INFO_PATH if your package uses a different location. However, this is not recommended. These entries contain just the path relative to PREFIX/INFO_PATH. For example, lang/gcc34 installs info files to PREFIX/INFO_PATH/gcc34, and INFO will be something like this:

Appropriate installation/de-installation code will be automatically added to the temporary pkg-plist before package registration.
