# now takes major and minor version arguments
#

#--common--------------------------------------------------------------

# Usage:  mklib <archflags> <libname> <major> <minor> <file.o ... >
#
# <archflags> are arcitecture specific build flags
# <libname> is name of output library (LIBRARY)
# <major> is major version number (MAJOR)
# <minor> is minor version number (MINOR)
# <file.o ... > remaining arguments are object files (OBJECTS)
# 
# added local installation target prefix (RM_INSTALL)
# tidied up the build
