=head1 NAME

ExtUtils::Mkbootstrap - make a bootstrap file for use by DynaLoader

=head1 SYNOPSIS

C&lt;Mkbootstrap&gt;

=head1 DESCRIPTION

Mkbootstrap typically gets called from an extension Makefile.

There is no C&lt;*.bs&gt; file supplied with the extension. Instead, there may
be a C&lt;*_BS&gt; file which has code for the special cases, like posix for
berkeley db on the NeXT.

This file will get parsed, and produce a maybe empty
C&lt;@DynaLoader::dl_resolve_using&gt; 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 C&lt;@DynaLoader::dl_resolve_using&gt;
array.

The C&lt;*_BS&gt; file can put some code into the generated C&lt;*.bs&gt; file by
placing it in C&lt;$bscode&gt;. This is a handy 'escape' mechanism that may
prove useful in complex situations.

If @DynaLoader::dl_resolve_using contains C&lt;-L*&gt; or C&lt;-l*&gt; entries then
Mkbootstrap will automatically add a dl_findfile() call to the
generated C&lt;*.bs&gt; file.
