<h1><a name="description">DESCRIPTION</a></h1>
<p>Mkbootstrap typically gets called from an extension Makefile.</p>
<p>There is no <code>*.bs</code> file supplied with the extension. Instead, there may
be a <code>*_BS</code> file which has code for the special cases, like posix for
berkeley db on the NeXT.</p>
<p>This file will get parsed, and produce a maybe empty
<code>@DynaLoader::dl_resolve_using</code> array for the current architecture.
That will be extended by $BSLOADLIBS, which was computed by
ExtUtils::Liblist::ext(). If this array still is empty, we do nothing,
else we write a .bs file with an <code>@DynaLoader::dl_resolve_using</code>
array.</p>
<p>The <code>*_BS</code> file can put some code into the generated <code>*.bs</code> file by
placing it in <code>$bscode</code>. This is a handy 'escape' mechanism that may
prove useful in complex situations.</p>
<p>If @DynaLoader::dl_resolve_using contains <code>-L*</code> or <code>-l*</code> entries then
Mkbootstrap will automatically add a <code>dl_findfile()</code> call to the
generated <code>*.bs</code> file.</p>
