====== Подсветка кода программ ======

Подсветка синтаксиса исходных текстов программ делается с помощью пары тегов <nowiki><code>..</code></nowiki>, в которые он должен обрамляться. При этом сохранятся отступы и прочее форматирование исходного текста. В данном случае не указан 
язык программирования, поэтому текст будет подсвечиваться одинаково для всех символов.

Если указать язык программирования\\
<nowiki><code %lang%>..</code></nowiki>
\\ , то текст программы будет подсвечен в соответствие с предопределённой схемой подсветки синтаксиса данного языка.

Параметр ''%lang%'' может быть одним из следующего списка предопределённых языков программирования:

<code>
actionscript
actionscript-french
ada
apache
applescript

asp
