+     <listitem><para>List of compression types which are understood by the acquire methods.
+     Files like <filename>Packages</filename> can be available in various compression formats.
+     This list defines in which order the acquire methods will try to download these files.
+     Per default <command>bzip2</command> compressed files will be prefered over
+     <command>lzma</command>, <command>gzip</command> and uncompressed files. The syntax for
+     the configuration fileentry is
+     <synopsis>Acquire::CompressionTypes::<replaceable>FileExtension</replaceable> "<replaceable>Methodname</replaceable>";</synopsis>
+     e.g. <synopsis>Acquire::CompressionTypes::bz2 "bzip2";</synopsis>
+     Note that at runtime the <literal>Dir::Bin::<replaceable>Methodname</replaceable></literal> will
+     be checked: If this setting exists the method will only be used if this file exists, e.g. for
+     the bzip2 method above (the inbuilt) setting is <literallayout>Dir::Bin::bzip2 "/bin/bzip2";</literallayout>
