Distribution: Freeware

InstallerNG is a 100% compatible replacement of the original C= Installer provided
with the old OS 3.1 releases.
InstallerNG is completly written from scratch with many new features and bugfixes
where the old Installer is just a pitty. Additionally, it has a formal language
definition, which is the reason for a stable compiler-kernel and the good interpreter.
Also InstallerNG could be the new Installer in upcoming OS release (AmigaOS v3.6+)

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
!!! Please note that this is a PRERELEASE and not a final version !!!
!!! It could have bugs where you adviced to report them to us.    !!!

Please take a look at it and have fun...

Some of the new features are:
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- Nice GUI
    The builtin-gui is based on a BOOPSI class-collection, which was also written
    by Jens Tröger; these classes allow easy font-adaption, resizing and support
    MagicWB. Additionally, you may "plug-in" other gui-systems (like MUI, BGui, ...)
    via a shared library named "installergui.library".
    Furthermore, the help window can stay open, while you install your packages;
    this is a builtin feature and should be provided by every GUI

- More strict interpretation
    InstallerNG is more compatible to the C= documented Installer script language.
    The original C= Installer v43+ isn`t really strict in interpreting scripts and
    many error are just ignored and not mentioned to the user.

- Flexible interpretation
    If an error raises while the interpretation process, InstallerNG provides
    to continue at the very next function.

- Interuptable Interpretation
    The InstallerNG can be interupted everytime by sending the CTRL-F signal to its
    process. This option allows to break out of infinite loops.

- No restrictions
    The original installer has some terrible restrictions: maximum string-length,
    maximum size of a string value. The InstallerNG makes none of these:
    a string (and the value of a string variable too) can be as long as it fits
    into your memory.

- Comfortable WB-Start
    If you run the InstallerNG from WB and give it no script via tooltypes
    a requester pops up which asks you whether you want to load a script by a
    file-requester or if you want to app-iconify the installer. If you drop a
    script-file on the application icon the InstallerNG gets started.

- Returncode
    The InstallerNG now returns RETURN_OK (0) if everything of the installation
    went fine, or, in case of an error, it returns RETURN_FAIL (20). This could
    be useful, if you call the InstallerNG from a script and the script wants
    to check whether the InstallerNG was successfull or not.

- SOOP - Simple Object Oriented Programing
    With help of the new functions PUT-PROPERTY, GET-PROPERTY and REMOVE-PROPERTY the
    InstallerNG implements LISP-like property-lists for symbols. Imagine of a symbol
    as an object and the properties as the objects attributes. Furthermore, if you write
    PROCEDURE`s, which are able to operate on an object`s attributes, you just can produce
    simple OO code :)    ...without a class hierarchy, but object oriented!

- UNDO-REDO environments
    Using the function "SWING" you are able to build an environment, in which you can
    "swing" from one (topmost) function to the next. When reaching the last one, the
    installation may proceed. This looks/works much like the MS-Setup program :)

    With v44 of the C= installer, you are able to simulate such an environment by
    special TRACE/RETRACE/BACK functions (have a look at the C= installer documentation)

- Full installation control
    If you want to, the InstallerNG asks for confirmation of every action, no mattter
    what the script-programmer codes in his installer script

- AppWindow
    InstallerNG can now act as an socalled "AppWindow", i.e. you may drop files into
    the window and InstallerNG uses them. This only works, when the InstallerNG asks
    for a file or directory.
