Grail

README Page 1 of 3 Saved: Friday, March 26, 1999 1:31:36 PM GRAIL 0.6 ========= Grail(TM) is a web browser written in Python, an object-oriented scripting language. Grail is distributed in source form. It requires that you have a Python interpreter and a Tcl/Tk installation, with the Python interpreter configured for Tcl/Tk support.

The full text of the license can be found in the file LICENSE in this directory. The sources are Copyright (c) CNRI 1996-1999. Grail is a registered trademark of CNRI. Future development ------------------ Given the low usage of Grail, CNRI cannot allocate further resources to this project. The license allows for derivative projects, so anyone who has a need for a Python-based or easily modified Internet browser is free to use the Grail source code as a basis for a new project. The Grail development team would be happy to provide anyone seriously interested in using Grail as the basis for a new project with a copy of the CVS repository. We are also able to provide pointers from the Grail Web site to any new projects that spring up based on Grail. Hardware requirements --------------------- Grail runs on most Unix systems, on Windows NT and 95, and on Macintosh systems, provided you have enough memory and a fast enough machine. (For Windows, 32 Meg RAM and 90 MHz Pentium is a reasonable minimal configuration. For Macintosh, a 40 MHz 68k or any PPC, with 24 Meg RAM, is acceptable.) Installation ------------ There are three steps to take before you can use Grail: - Install Tcl and Tk. The versions must be compatible with each other and with the Python version you are installing in the next step; currently, the oldest Tcl/Tk version supported is 8.0. You can get Tcl/Tk it at http://www.scriptics.com/; or try ftp to ftp.sunlabs.com in directory /pub/tcl/. - Install Python 1.5 (or newer if available), configured for use with Tk. The URL to get Python is http://www.python.org/; or try ftp to ftp.python.org in directory /pub/python/src/. You must enable Tk support by editing the file Modules/Setup; see the comments in that file (search for "tkinter") and the main README that comes with Python. - Install the Grail sources in a convenient place. Grail is executed directly from its source directory. If you are using the /usr/local README Page 2 of 3 Saved: Friday, March 26, 1999 1:31:36 PM hierarchy, the Grail sources could be installed in /usr/local/lib/grail/. You can also choose to leave grail.py unchanged and have a shell script named "grail" which execs the Python interpreter, e.g.: exec pytho…
