#    NAME
#      genclntst.sh - Generate the client static library 
#
#    DESCRIPTION
#      This script generate the library libclntst10.a: a single static
#      library clients can use to link OCI, Pro*C, and XA applications
#
#    NOTES
#      This script assumes the client shared library has already been
#      generated and the linker map file for it has been saved to the
#      file ${LIB_DIR}/clntsh.map.  The map file is scanned to determine
#      the list of objects to include in the static library.
