"""
Provides include, which makes it easy to include other HTML into pages.

*DEPRECATED.*  Uses deprecated webhelpers.rails and is too trivial to port.

``Tired of regenerating HTML pages from templates? Want more from Web 
caches? HInclude makes one thing very easy; including other bits of HTML 
into your Web page, using the browser.``

Tip: Filter by directory path e.g. /media app.js to search for public/media/app.js.
Tip: Use camelCasing e.g. ProjME to search for ProjectModifiedEvent.java.
Tip: Filter by extension type e.g. /repo .js to search for all .js files in the /repo directory.
Tip: Separate your search with spaces e.g. /ssh pom.xml to search for src/ssh/pom.xml.
