+/* To use this file with libraries the following macros are useful:
+
+     #define _ASSUAN_EXT_SYM_PREFIX _foo_
+   
+     This prefixes all external symbols with "_foo_".
+
+     #define _ASSUAN_ONLY_GPG_ERRORS
+
+     If this is defined all old-style Assuan error codes are made
+     inactive as well as other dereacted stuff.
+
+   The follwing macros are used internally in the implementation of
+   libassuan:
+
+     #define _ASSUAN_NO_PTH 
+
+       This avoids inclusion of special GNU Pth hacks.
+
+     #define _ASSUAN_NO_FIXED_SIGNALS 
+
+       This disables changing of certain signal handler; i.e. SIGPIPE.
+
+     #define _ASSUAN_USE_DOUBLE_FORK
+
+       Use a double fork approach when connecting to a server through
+       a pipe.
