   MuiEnv uses MagicUserInterface, Copyright (C) 1993 Stefan Stuntz.

Requirements
************

   MuiEnv 1.2 needs version 2.04 (37.175) oder higher of the Amiga
Operating System.

   MuiEnv uses MagicUserInterface by Stefan Stuntz.  MagicUserInterface
is not included. You can find it as dev/gui/mui23usr.lha on Aminet.

Installation
************

   For installation, simply copy the program MuiEnv to a directory in
the path.

   As external editor for environment variables $EDITOR is used. So
you must set the EDITOR variable with SetEnv EDITOR program
name or with MuiEnv.

Usage
*****

   MuiEnv opens a window with a listview, a string gadget and several
button gadgets.

   The listview shows the current environment variable, that can be
chosen by arrow keys or by mouse.

   With TAB you can switch between the listview and the string gadget.
The contents of the string gadget are valid for all actions.

   With RETURN or a double click inside the listview you can change to
a subdirectory if a directory is selected, if a short variable is
selected, the Edit button is triggered, if a long variable or a
Variable containing Null-bytes is selected, the Edit ext. button is
triggered.  This is functioning, too, if the string gadget is activated.

   The Edit button opens a new window with a string gadget to change
the current environment variable and three button gadgets: Save saves
the environment variable to ENV: and ENVARC:, Use saves only to
ENV: and Cancel cancels.

   The Edit ext. button calls an external editor to edit the contents
of the current environment variable.  The editor can be determined with
the ToolType EDITOR.  Default is $EDITOR.

   The Save button copies the current environment variable from
ENV: to ENVARC:.

   The Reload button copies the current environment variable from
ENVARC: to ENV:.

   the Delete button deletes the current environment variable in
ENV: and ENVARC:. It deletes a directory completely with
contents.

   The Rename button opens a new window with a string gadget to change
the name of the current environment variable and three button gadgets:
Save renames the environment variable in ENV: and ENVARC:,
Use renames only in ENV: and Cancel cancels.

   The MakeDir button opens a new window with a string gadget to
create a new directory and three button gadgets: Save creates the
directory in ENV: and ENVARC:, Use creates only in ENV: and
Cancel cancels.

   The Rescan button rereads the contents of the listview.

   The Parent button shows the contents of the parent directory in
the listview.

   The About button displays information about MuiEnv.

   The Quit button quits MuiEnv.

   New variables a created by inserting an new variable name in the
string gadget and pressing Edit or RETURN.
