Shared Library (with on/off toggling via a Control Panel) that speeds
up PowerMacs.

From the v1.1.1 ReadMe, included with download #1:

> PowerLib 1.1.1 is a freeware control panel which may enhance the
> performance of certain applications, when run under the
> PowerMacintosh platform.
>
> ? What is PowerLib 1.1.1?
>
> Macintosh applications use modules known as shared libraries. These
> libraries are stored within the system file. Most applications are
> written to make use of these shared libraries, in order to cut down
> on file size and disk accessing time (this is why Macintosh files
> often take up less room on the hard drive, yet the operating system
> occupies a large segment of RAM). Due to the hardware differences
> which exist between the PowerMacintosh line of Apple computers, and
> the various other models (e.g. Centris, Quadra, Performa, etc.) some
> of the system software runs under emulation on PowerMacintosh
> computers. Obviously, this is an inefficient way to manage the
> system's resources. PowerLib 1.1.1 will intercept certain calls to
> the system file when applications require the use of the shared
> libraries which are not directly supported by the PowerMacintosh
> platform. This helps to compensate for the differences which exist
> between the PowerMacintosh line of computers and the older Macintosh
> brands. When PowerLib 1.1.1 is installed, users may experience an
> increase in apparent speed, when running certain applications which
> make use of non-PowerMacintosh libraries.
>
> ? To install PowerLib 1.1.1:
>
> Simply place the files in the System Folder. Your Macintosh will
> automatically place the PowerLib Control Panel in the control panel
> folder. The included extension, ADSP (Apple Data Stream Protocol),
> is optional and only of use to those users connected to an AppleTalk
> or LocalTalk network. PowerLib 1.1.1 will use this extension to
> enhance the performance of network-related applications. If you are
> not connected to a network, this extension will not affect your
> system (aside from taking up memory).
>
> ? To use PowerLib 1.1.1:
>
> Once PowerLib 1.1.1 is installed, it requires no user input.
> PowerLib 1.1.1 will automatically determine Macintosh system on
> which it runs. One can open the control panel and disable or enable
> the program's operation (you must restart your system in order for
> changes to take effect).

> ? Release Notes:
