+This directory contains a browser written in Python for "Info files"
+as used by the Emacs documentation system.  The browser requires that
+Python is built with the "stdwin" option and runs under X11 or the
+Mac window system.
+
+Now you can read Info files even if you can't spare the memory, time or
+disk space to run Emacs.  (I have used this extensively on a Macintosh
+with 1 Megabyte main memory and a 20 Meg harddisk.)
+
+You can give this to someone with great fear of complex computer
+systems, as long as they can use a mouse.
+
+Another reason to use this is to encourage the use of Info for on-line
+documentation of software that is not related to Emacs or GNU.
+(In particular, I plan to redo the Python and STDWIN documentation
+in texinfo.)
+
+The main program is in file "ib.py"; this accepts a file name and a
+node name as optional command line arguments, i.e., its usage is
+
+	python ib.py [file [node]]
+
+
+Configuration:
+
+- The pathname of the directory (or directories) containing
+the standard Info files should be set by editing the
+value assigned to INFOPATH in module ifile.py.
+
+- The default font should be set by editing the value of FONT
+in this module (ibrowse.py).
+
+- For fastest I/O, you may look at BLOCKSIZE and a few other
+constants in ifile.py.
