=head1 NAME

|
|
Package WebGUI::Asset::Snippet
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
Provides a mechanism to publish arbitrary code snippets to WebGUI for reuse in other pages. Can be used for things like HTML segments, javascript, and cascading style sheets. You can also specify the MIME type of the snippet, allowing you to serve XML, CSS and other text files directly from the WebGUI asset system and have browsers recognize them correctly.
