** SETTING: robot-restrict                width=40 block-text
** The VALUE of this setting is a list of GLOB patterns that match
** pages for which complex HTTP requests from unauthenicated clients
** should be disallowed.  "Unauthenticated" means the user is "nobody".
** The recommended value for this setting is:
**
**     timelineX,diff,annotate,zip,fileage,file,finfo,reports
**
** The "diff" tag covers all diffing pages such as /vdiff, /fdiff, and
** /vpatch.  The "annotate" tag also covers /blame and /praise.  "zip"
** also covers /tarball and /sqlar.  If a tag has an "X" character appended,
** then it only applies if query parameters are such that the page is
** particularly difficult to compute. In all other case, the tag should
** exactly match the page name.
