An swiss knife of extensions for the AppleScript engine.
From the author's webpage:
> What is Jon's Commands?
> Jon's Commands provides added functionality in the form of about 30
> commands which can be called from AppleScript. To examine the
> AppleScript syntax of each of the commands, simply drag the Jon's
> Commands file onto the Script Editor (or one of the commercial
> script editors), or use the Open Dictionary command to open Jon's
> Commands. To install Jon's Commands, simply drop it into the
> Scripting Additions folder inside your Extensions folder which is in
> your System Folder.
>
> Is this all the documentation there is?
> Of course not. The file "Jon's Commands Reference" is an Apple
> Guide file. It contains a quick reference of all the commands'
> syntax, examples and explanations. It is designed to be used in your
> script editor. This file is a replacement for the SimpleText files I
> used to use which were becoming cumbersome and difficult to
> navigate. It contains explanations of each command and example
> scripts.
>
> You install the "Jon's Commands Reference" guide by placing it, or
> an alias to it, in the same folder as your script editor. "Jon's
> Commands Reference" will then appear in the help menu on the right
> side of your menu bar after you restart the script editor.
>
> This guide is especially useful with Script Debugger, available from
> Late Night Software, since that editor is scriptable. In all other
> editors, when you press the Copy button a copy of the current
> command's complete syntax is placed on the clipboard for you to
> paste into your script (after a brief switch to the Finder). In
> Script Debugger, the text will be placed directly into the front
> script window, without the annoying switch to the Finder and back
> which is necessary with the other editors. Jon's Commands needs to
> be installed for the Copy feature to work properly with any editor
> besides Script Debugger, as does the scriptable Finder.
