 *   - class            The class name for the repository. May come from the core or an extension.
 *                      The core repository classes are LocalRepo, ForeignDBRepo, FSRepo.
 *
 *   - name                 A unique name for the repository.
 *
 * For most core repos:
 *   - url              Base public URL
 *   - hashLevels       The number of directory levels for hash-based division of files
 *   - thumbScriptUrl   The URL for thumb.php (optional, not recommended)
 *   - transformVia404  Whether to skip media file transformation on parse and rely on a 404
 *                      handler instead.
 *   - initialCapital   Equivalent to $wgCapitalLinks (or $wgCapitalLinkOverrides[NS_FILE],
 *                      determines whether filenames implicitly start with a capital letter.
 *                      The current implementation may give incorrect description page links
 *                      when the local $wgCapitalLinks and initialCapital are mismatched.
 *   - pathDisclosureProtection
 *                      May be 'paranoid' to remove all parameters from error messages, 'none' to
 *                      leave the paths in unchanged, or 'simple' to replace paths with
 *                      placeholders. Default for LocalRepo is 'simple'.
 *   - fileMode         This allows wikis to set the file mode when uploading/moving files. Default
 *                      is 0644.
 *   - directory        The local filesystem directory where public files are stored. Not used for
 *                      some remote repos.
 *   - thumbDir         The base thumbnail directory. Defaults to <directory>/thumb.
 *   - thumbUrl         The base thumbnail URL. Defaults to <url>/thumb.
 *
 *
 * These settings describe a foreign MediaWiki installation. They are optional, and will be ignored
 * for local repositories:

 *                       http://en.wikipedia.org/w
 *   - scriptExtension   Script extension of the MediaWiki installation, equivalent to
 *                       $wgScriptExtension, e.g. .php5 defaults to .php
 *
 *   - articleUrl        Equivalent to $wgArticlePath, e.g. http://en.wikipedia.org/wiki/$1
 *   - fetchDescription  Fetch the text of the remote file description page. Equivalent to
 *                      $wgFetchCommonsDescriptions.
 *
 * ForeignDBRepo:
 *   - dbType, dbServer, dbUser, dbPassword, dbName, dbFlags
 *                      equivalent to the corresponding member of $wgDBservers
 *   - tablePrefix       Table prefix, the foreign wiki's $wgDBprefix
 *   - hasSharedCache    True if the wiki's shared cache is accessible via the local $wgMemc
 *
 * ForeignAPIRepo:
 *   - apibase              Use for the foreign API's URL
 *   - apiThumbCacheExpiry  How long to locally cache thumbs for

 *   - An exit code mapped to AV_SCAN_ABORTED causes the function to consider

 *   - An exit code mapped to AV_NO_VIRUS will cause the file to pass, meaning
 *     no virus was found.
 *   - All other codes (like AV_VIRUS_FOUND) will cause the function to report
 *     a virus.
 *   - You may use "*" as a key in the array to catch all exit codes not mapped otherwise.
