The World's Most Successful Programming Language. A mode for editing Microsoft Visual Basic project files. Really has little to do with editing but exists, principally, to automatically load the files belonging to the project. Do not allow any tabs into the file. Load files named in module and class lines of vbp files and project lines of vbg files.
Match tells which element to use as the file name.
If the file name is relative it is relative to the directory containing the current buffer. If the file is already loaded nothing happens, this prevents circular references causing trouble. Modifies point so use inside save-excursion. Load file if not already loaded.
