*:: =src/classad/README=: first line
 *:: =src/classad/new_classad.cpp=: ClassAdLibraryVersion() *Update both functions with this name!*
 
+*: Update the shared library version number in =src/classad/Makefile.am.m4=. Look for these two lines:
+{code}
+libclassad_la_LDFLAGS = -version-info 1:0:0
+libclassad_ns_la_LDFLAGS = -version-info 1:0:0
+{endcode}
+If the ABI has changed, you should increment the first number and set the second and third ones to zero. If the ABI hasn't changed, then increment the second or third number. See http://tldp.org/HOWTO/Program-Library-HOWTO/shared-libraries.html#AEN135 for examples of things that will change the ABI.
