I'm finding it difficult to work with a 6,000+ line Tcl script and not go insane while looking for a particular block of code. Since most of the program is organized into different units of functionality and not all users will need all units immediately on startup we can improve things by splitting procs out into multiple files and let auto_load handle things for us. This should help not only to better organize the source, but it may also improve startup times for some users as the Tcl parser does not need to read as much script before it can show the UI. In many cases the user can avoid reading at least half of git-gui now. Unfortunately we now need a library directory in our runtime location. This is currently assumed to be $(sharedir)/git-gui/lib and its expected that the Makefile invoker will setup some sort of reasonable sharedir value for us, or let us assume its going to be $(gitexecdir)/../share. We now also require a tclsh (in TCL_PATH) to just run the Makefile, as we use tclsh to generate the tclIndex for our lib directory. I'm hoping this is not an unncessary burden on end-users who are building from source. I haven't really made any functionality changes here, this is just a huge migration of code from one file to many smaller files. All of the new changes are to setup the library path and install the library files. Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
