 Compilation and installation
 

-The primary output of the source here is the libyaz.a library, which
-contain support functions for implementing the server or client role
-of Z39.50/SR. Currently, the library is placed in a directory 'lib'
-which is one level *above* the distribution directory (yaz). This was
-initially done because the library is often used along with several
-other packages, and it was useful to gather the different libraries in
-a common place. If you don't like it, changing the 'LIBDIR' macro in
-the toplevel makefile should be sufficient. Obscurely, the header
-files are located in the include-directory *under* the yaz/ directory.
-
-The toplevel makefile also contains directions on how to enable Peter
-Furniss' XTIMOSI package. The package can be downloaded from
-ftp://pluto.ulcc.ac.uk/ulcc/thinosi/... (or something close to that).
-If you place the xtimosi directory on the same level as the yaz
-directory, and simply follow the directions in the toplevel YAZ
-makefile, the libmosi.a library from xtimosi should link in with no
-problems. The xtimosi library is needed to support a full OSI stack,
-but is *not* required to talk to American-style Z39.50 implementations
-over TCP/IP. Don't worry about compiling the test applications in the
-xtimosi package. Just do a "make libmosi.a", and do whatever is
-required to make the compilation complete on your local ystem.
