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