To make it short: most people can execute | # yum install libextractor-plugins to install a full-featured 'libextractor' library. By executing | # yum install libextractor-plugins-base instead of, only base plugins will installed. This costs some functionality (because some filetypes will not be supported) but it avoids expensive dependencies. It is possible to install only a subset of the expensive plugins (and their dependencies), too. The libextractor library is split into the following Fedora packages: * 'libextractor' ... the main package containing only the base library and small utilities. * 'libextractor-devel' ... contains the usual development stuff * 'libextractor-plugins' ... this is a meta package which brings in all available plugins shipped by the upstream project * 'libextractor-plugins-base' ... a set of plugins which require only a minimal amount of foreign libraries * 'libextractor-plugins-XXX' ... plugins which support certain filetypes but have additional dependencies Please report (packaging-related) bugs at http://bugzilla.redhat.com; Enrico Scholz is the author of this document.
