Installation mode

The installation has a basic mode and an advanced mode. The basic mode
is accessed by clicking the Install button on the license dialog
after checking the Terms and Conditions checkbox. The software is
then installed with no further questions for the current user using
a default directory and default set of packages.

The advanced mode is accessed by clicking the Advanced button on the
license dialog. This allows the user to select the installation scope
(see below), the directory for installation as well as which packages
are to be installed.

Installation scope

If advanced mode is selected, the user is given a choice of installing
the software only for the current user or machine wide for all users.
Please see the requirements listed in the dialog before making a selection.

Shortcuts, paths and file associations

In both basic and advanced modes the installer will make the following
changes by default.

Shortcuts to the Tcl executables and documentation will be added to
the Start menu.

The PATH environment variable will be modified to include the directory
containing the Tcl executables.

The extensions .tclapp and .tkapp will be associated with the Tcl
console mode executable tclsh.exe and GUI executable wish.exe respectively.

In all cases, the modifications will be made for a single user or
machine wide depending on the installation scope selected.

Any of these features can be deselected in advanced mode via the Features
