**     entry in the repository that is associated with the remote URL store.
**     Passwords are obscured in the output.
**
** > fossil remote delete NAME
**
**     Delete a named URL previously created by the "add" subcommand.
**
** > fossil remote hyperlink ?FILENAME? ?LINENUM? ?LINENUM?
**
**     Print a URL that will access the current checkout on the remote
**     repository.  Or if the FILENAME argument is included, print the
**     URL to access that particular file within the current checkout.
**     If one or two linenumber arguments are provided after the filename,
**     then the URL is for the line or range of lines specified.
**
** > fossil remote list|ls
**
**     Show all remote repository URLs.
**
** > fossil remote off
**
**     Forget the default URL. This disables autosync. 

**
** > fossil remote scrub
**
**     Forget any saved passwords for remote repositories, but continue
**     to remember the URLs themselves.  You will be prompted for the
**     password the next time it is needed.
**
** > fossil remote ui ?FILENAME? ?LINENUM? ?LINENUM?
**
**     Bring up a web browser pointing at the remote repository, and
**     specifically to the page that describes the current checkout
**     on that remote repository.  Or if FILENAME and/or LINENUM arguments
**     are provided, to the specific file and range of lines.  This
**     command is similar to "fossil remote hyperlink" except that instead
**     of printing the URL, it passes the URL off to the web browser.
**
** > fossil remote REF
**
**     Make REF the new default URL, replacing the prior default.
**     REF may be a URL or a NAME from a prior "add".
