The importTextFiles.php maintenance script, which reads text files from disk and imports them as pages on the wiki, currently only supports three options: --user, --summary, --use-timestamp.

Your task is to add a few additional options to this script:

• --bot: Whether to mark the edit as a bot edit. (This may require extending WikiRevision to provide this functionality.)
• --overwrite: Whether to overwrite existing pages. (The default behaviour is to skip pages that already exist.) If --use-timestamp is also supplied, the script should skip pages whose current revision is more recent than the file's timestamp.
• --prefix: A string to place in front of the file name. Examples: "Template:", "MyData/", "Template:Meteorological observations " (with final space).
• --rc: If supplied, entries should be placed in Recent Changes for the newly created revisions. (By default, this is not done.)
