To prevent having to use epochs for every new upstream

- linking). Also, they're <em>essential</em> for programs
- using <tt>libltdl</tt>.<footnote>
- Although <prgn>libtool</prgn> is fully capable of
- linking against shared libraries which don't have
- <tt>.la</tt> files, as it is a mere shell script it can
- add considerably to the build time of a
- <prgn>libtool</prgn>-using package if that shell script
- has to derive all this information from first principles
- for each library every time it is linked. With the
- advent of <prgn>libtool</prgn> version 1.4 (and to a
- lesser extent <prgn>libtool</prgn> version 1.3), the
- <file>.la</file> files also store information about
- inter-library dependencies which cannot necessarily be
- derived after the <file>.la</file> file is deleted.
+ Packages that use <prgn>libtool</prgn> to create and install
+ their shared libraries install a file containing additional
+ metadata (ending in <file>.la</file>) alongside the library.
+ For public libraries intended for use by other packages, these
+ files normally should not be included in the Debian package,
+ since the information they include is not necessary to link with
+ the shared library on Debian and can add unnecessary additional
+ dependencies to other programs or libraries.<footnote>
+ These files store, among other things, all libraries on which
+ that shared library depends. Unfortunately, if
+ the <file>.la</file> file is present and contains that
+ dependency information, using <prgn>libtool</prgn> when
+ linking against that library will cause the resulting program
+ or library to be linked against those dependencies as well,
+ even if this is unnecessary. This can create unneeded
+ dependencies on shared library packages that would otherwise
+ be hidden behind the library ABI, and can make library
+ transitions to new SONAMEs unnecessarily complicated and
+ difficult to manage.
</footnote>
+ If the <file>.la</file> file is required for that library (if,
+ for instance, it's loaded via <tt>libltdl</tt> in a way that
+ requires that meta-information), the <tt>dependency_libs</tt>
+ setting in the <file>.la</file> file should normally be set to
+ the empty string. If the shared library development package has
+ historically included the <file>.la</file>, it must be retained
+ in the development package (with <tt>dependency_libs</tt>
+ emptied) until all libraries that depend on it have removed or
+ emptied <tt>dependency_libs</tt> in their <file>.la</file>
+ files to prevent linking with those other libraries
+ using <prgn>libtool</prgn> from failing.
+ </p>
+
+ <p>
+ If the <file>.la</file> must be included, it should be included
+ in the development (<tt>-dev</tt>) package, unless the library
