NAME

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

SYNOPSIS

         Mkbootstrap

DESCRIPTION

       Mkbootstrap typically gets called from an extension Makefile.

       There is no "*.bs" file supplied with the extension. Instead, there may be a *_BS 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 @DynaLoader::dl_resolve_using 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 @DynaLoader::dl_resolve_using array.

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

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