comparison dw.hpp @ 2861:ef7a414f9b71

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Add initial C++ binding header and example program. Still trying to figure out how it will work, but it is loosely based on GTK-- and when complete dwtestoo will replicate dwtest. Added support for building dwtestoo on Unix and Mac.
