#    NAME
#      genagtsh.sh - Generate an agent shared library
#
#    DESCRIPTION
#
#  Invocation:
#
#	genagtsh.sh  lib_name agent_version hs_driver
#
#	lib_name:	Filename of library to generate;
#			typically, $(LIBAGTSH) as used in the
#			RDBMS Makefile.  E.g., "libagtsh.so"
#
#	lib_version:	Version of the shared library
#
#			On UNIX ".agent_version" is appended to
#			the shared-library filename.  E.g., "1.0"
#
#
#    NOTES
#	This is a remote descendent of the script used to generate
#	the client shared library, libclntsh.so.
