# This is the main target for building shared libraries. It takes the following actions
#   a) Create 'tmp-petsc-shlib' in the library directory
#   b) Loops over the shared libraries in $SHLIBS
#   c) Checks that the corresponding archive or its libtool counterpart exists
#   d) Checks whether an existing archive is newer than the shared library
#   e) Executes target 'shared_arch' for any out-of-date library (The library basename is passed as LIBNAME)
#   c) Removes 'tmp-petsc-shlib'
# The 'shared_arch' target is passed
#   a) LIBNAME (the library basename)
#   b) SHARED_LIBRARY_TMPDIR (where .o files should be manipulated)
# and both the archive and shared library reside in INSTALL_LIB_DIR.
