from_svn is twanager command that can retrieve content from an http or file URL and put that content into a bag named in the arguments. The name of the command comes from the type of content it handles: it retrieves .tiddler, .js and .recipe files in the format used in the TiddlyWiki subversion repository. However, the content does not need to be located in the TiddlyWiki repo, it can be anywhere an http, https, or file url can reach.

If a recipe file is retrieved, it will traverse the recipe and retrieve the tiddlers and javascript named therein.

from_svn is a very useful way to populate a TiddlyWeb installation with existing TiddlyWiki content.
