: This utility was only used by the old Makefile.SH extension
: mechanism.  It is now obsolete and may be removed in a future
: release.
:
: This utility takes a list of libraries in the form
: -llib1 -llib2 -llib3
: and prints out lines suitable for inclusion in an extension
: Makefile.  
: Extra library paths may be included with the form -L/another/path
: this will affect the searches for all subsequent libraries.
:
: It is intended to be "dotted" from within an extension Makefile.SH.
: see ext/POSIX/Makefile.SH for an example.
: Prior to calling this, the variable potential_libs should be set 
: to the potential list of libraries
:
: It sets the following
: extralibs = full list of libraries needed for static linking.
:		Only those libraries that actually exist are included.
: dynaloadlibs = full path names of those libraries that are needed 
:		but can be linked in dynamically on this platform.  On 
:		SunOS, for example, this would be .so* libraries, 
:		but not archive libraries.
:		Eventually, this list can be used to write a bootstrap file.
: statloadlibs = list of those libraries which must be statically
:		linked into the shared library.  On SunOS 4.1.3, 
:		for example,  I have only an archive version of
:		-lm, and it must be linked in statically.
:
:  This script uses config.sh variables libs, libpth, and so.  It is mostly
:  taken from the metaconfig libs.U unit.
