    Define macros for abbreviations and other "aliases", and then embed them in the rest of your tiddler content to quickly insert common terms, phrases and links without a lot of repetitive typing.
    !!!!!Usage
    <<<
    {{{
    <<alias keyword "content to display">>
    }}}
    Select a short keyword or other abbreviated term that is easily input with just a few keystrokes.  When the {{{<<alias>>}}} macro is processed, it creates a new macro for you to embed in tiddler content, using the specified alias keyword as the name for that new macro.  You can choose any keyword you like, but don't include any spaces, as macro names must not contain spaces.

    In order to ensure that your aliases are always defined and available for use, you should add your definitions to a tiddler that you are certain will be displayed when your TW is first loaded (e.g., [[MainMenu]]).  The {{{<<alias>>}}} macro itself won't actually produce any visible output, so it can be safely added to practically any tiddler without producing a change in that tiddler's appearance.

    To use the aliases you have defined, simply invoke them as you would any other TiddlyWiki macro, e.g.,
    {{{<<keyword>>}}}.  If you include parameters when you invoke the macro -- {{{<<keyword param param param...>>}}} -- they can be inserted direclty into the output by replacing corresponding substitution markers, indicated by using "%0" through "%9" in the "text to display" parameter used when the alias was defined.  For example, to define a quick alias for inserting a link to any given subject on www.wikipedia.com, you can write:
    {{{
    <<alias wikipedia "[[Wikipedia:%0|http://www.wikipedia.com/wiki/%0]]">>
    }}}
    which allows you to then write:
    {{{
    <<wikipedia TiddlyWiki>>
    }}}
    which is processed as if you wrote:
    {{{
    [[Wikipedia:TiddlyWiki|http://www.wikipedia.com/wiki/TiddlyWiki]]
    }}}
    and is displayed this way:
    ><<alias wikipedia "[[Wikipedia:%0|http://www.wikipedia.com/wiki/%0]]">><<wikipedia TiddlyWiki>>

    Another interesting example uses the substitution markers to automatically display a reference to a TiddlerSlice value:
    {{{
    <<alias describe {{"|\<\<tiddler [[%0::Description]]\>\>|\n"}}>>
    }}}
    which allows you to then write:
    {{{
    <<describe AliasPlugin>>
    }}}
    which is processed as if you wrote:
    {{{
    |<<tiddler [[AliasPlugin::Description]]>>|
    }}}
    and is displayed this way:
    <<alias describe {{"|\<\<tiddler [[%0::Description]]\>\>|\n"}}>><<describe AliasPlugin>>
    <<<
    !!!!!Revisions
    <<<
    2009.09.09 1.1.1 'tiddler' arg passed to wikify() so aliases containing macros render with correct context
    2008.03.11 [*.*.*] plugin size reduction - documentation moved to [[AliasPluginInfo]]
    2007.03.21 1.1.0 added support for parameter substitution into alias macros, using format() method and%0..%9 markers
    2005.10.09 1.0.3 combined documentation and code into a single tiddler
    2005.08.12 1.0.0 initial release

    This plugin for ~TiddlyWiki >=2.5 provides an easy way to:

    # translate ~LaTeX math equations to ~MathML;
    # produce mathematical SVG graphics.

    If you use MS Internet Explorer, you may need the [[MathPlayer|http://www.dessci.com/en/products/mathplayer/download.htm]] plugin to render ~MathML.

    To get started with this blank [[TiddlyWiki]], you'll need to modify the following tiddlers:
    * [[SiteTitle]] & [[SiteSubtitle]]: The title and subtitle of the site, as shown above (after saving, they will also appear in the browser title bar)
    * [[MainMenu]]: The menu (usually on the left)
    * [[DefaultTiddlers]]: Contains the names of the tiddlers that you want to appear when the TiddlyWiki is opened
    You'll also need to enter your username for signing your edits: <<option txtUserName>>
