75 ><P
76 >LWTOOLS also includes a tool for managing libraries. These are analogous to
77 the static libraries created with the "ar" tool on POSIX systems. Each library
78 file contains one or more object files. The linker will treat the object
79 files within a library as though they had been specified individually on
80 the command line except when resolving external references. External references
81 are looked up first within the object files within the library and then, if
82 not found, the usual lookup based on the order the files are specified on
83 the command line occurs.</P

97 options, the first non-option argument is the name of the archive. All other
98 non-option arguments are the names of files to operate on.</P
