Synopsis
</h2>
<p class="indent" style="white-space:nowrap;">
<code>adl_COMPUTE_STANDARD_RELATIVE_PATHS</code>
</p>
<h2>
Description
</h2>
<div class="indent">
<p>
Here is the standard hierarchy of paths, as defined by the GNU Coding
Standards:
</p>
<pre>
prefix
exec_prefix
bindir
libdir
libexecdir
sbindir
datadir
sysconfdir
sharestatedir
localstatedir
infodir
lispdir
includedir
oldincludedir
mandir
</pre>
<p>
This macro will setup a set of variables of the form
'xxx_forward_relative_path' and 'xxx_backward_relative_path' where xxx is
one of the above directories. The latter variable is set to the relative
path to go from xxx to its parent directory, while the former hold the
other way.
</p>
<p>
For instance `bindir_relative_path' will contains the value to add to
$exec_prefix to reach the $bindir directory (usually 'bin'), and
`bindir_backward_relative_path' the value to append to $bindir to reach the
$exec_prefix directory (usually '..').
</p>
<p>
This macro requires adl_COMPUTE_RELATIVE_PATHS which itself requires
adl_NORMALIZE_PATH.
