Please see the NEWS file and the ChangeLog for detailed information on changes since 0.6.0.
See the README.vcs for instructions on how to build this.
v0.7.4 includes 'qof.pc' in advance of libqof2 to ease the imminent transition - packages can now check for 'qof' via pkg-config (instead of 'qof-1') and still build against libqof2 when qof-1.pc is removed.
The QOF documentation is entirely embedded in the source code. You can build an html version of the documentation by installing the 'doxygen' package, and then 'cd doc; make doc'. Skim the doc/README file for more info.
