This delta imposes two major changes on the C++ hierarchy:
- adds autoconf, automake, libtool support
- makes the hierarchy flatter and renames a few files (e.g., Queue.h,
Queue.cpp) that appeared twice, once under client/ and again under broker/.
In the process, I've changed many #include directives, mostly
to remove a qpid/ or qpid/framing/ prefix from the file name argument.
Although most changes were to .cpp and .h files under qpid/cpp/, there
were also several to template files under qpid/gentools, and even one
to CppGenerator.java.
Nearly all files are moved to a new position in the hierarchy.
The new hierarchy looks like this:
src # this is the new home of qpidd.cpp
tests # all tests are here. See Makefile.am.
gen # As before, all generated files go here.
lib # This is just a container for the 3 lib dirs:
lib/client
lib/broker
lib/common
lib/common/framing
lib/common/sys
lib/common/sys/posix
lib/common/sys/apr
