-Portability
------------
-
-Portability is a library used by the Network Weather System (NWS). It
-aims to be portable and to mask sockets, threads and other low level,
-system dependent calls. It can be used independetly from the NWS, but
-documentation is quite scarse: the header files will be your best
-friends.
-
-Compiling and installing
-------------------------
-
-To compile Portability run
- ./configure
- make all
-and you will find a library libNwsPortability.a and the needed file in
-the ./build-<your-architecture>/{lib,include}. You can install them with
- make install
-
-You can configure where to install library and includes using --prefix
-etc ... (./configure --help for the options).
-
-You can configure Portability to be used with threads (--enable-threads)
-and to disable sigalarm (--disable-sigalarm).
-
-
-
-Adaptive Timeouts
------------------
-
-Some of Portability's functions take a timeout as argument. Portability
-provides a way to use adaptive timeouts: look at timeouts.h for the
-interface. In short you can use GetTimeOut to get a timeout estimate that
-is more accurate the more information you give Portability through
-SetTimeOut. If you call the Send{MessageAnd}Data with a timeout of -1
-you'll get the adaptive timeouts without having to tinker with Get/Set
-TimeOut.
