Just had a whole lot of mysterious trouble (see here: Beta release of Inform App for Linux - #26 by neroden ) because of an undocumented dependency on rsync when doing make forceintegration. Rsync is not necessarily installed on an average Linux system.
The problem is buried quite deep, inside inweb/foundation_module/Chapter 1, which assumes the presence of rsync without checking.
There’s nothing wrong with depending on rsync (it’s easy enough to install on any Linux system), but it should be documented. Please add a description of the rsync dependency to the documentation for inweb, and to the build documentation for inform7.
