Fossil

** "new-name" term means that the cloned repository will be called
** "new-name.fossil".
**
** Options:
**   --empty           Initialize checkout as being empty, but still connected
**                     with the local repository. If you commit this checkout,
**                     it will become a new "initial" commit in the repository.
**   -f|--force        Continue with the open even if the working directory is
**                     not empty.
**   --force-missing   Force opening a repository with missing content
**   --keep            Only modify the manifest and manifest.uuid files
**   --nested          Allow opening a repository inside an opened checkout
**   --repodir DIR     If REPOSITORY is a URI that will be cloned, store
**                     the clone in DIR rather than in "."
**   --setmtime        Set timestamps of all files to match their SCM-side

/*
** COMMAND: backup*
**
** Usage: %fossil backup ?OPTIONS? FILE|DIRECTORY
**
** Make a backup of the repository into the named file or into the named
** directory.  This backup is guaranteed to be consistent even if there are
** concurrent changes taking place on the repository.  In other words, it
** is safe to run "fossil backup" on a repository that is in active use.
**
** Only the main repository database is backed up by this command.  The
** open checkout file (if any) is not saved.  Nor is the global configuration
** database.
**
** Options:
**
**    --overwrite              OK to overwrite an existing file
**    -R NAME                  Filename of the repository to backup

The green parts are *usually* generated by Fossil.  The blue parts
are things that you, the administrator, get to modify in order to
customize the skin.

Fossil *usually* (but not always - [see below](#override))
generates the initial HTML Header section of a page.  The
generated HTML Header will look something like this:

         <html>
         <head>
         <base href="..." />
         <meta http-equiv="Content-Security-Policy" content="...." />
         <meta name="viewport" content="width=device-width, initial-scale=1.0">
         <title>....</title>
         <link rel="stylesheet" href="..." type="text/css" />
         </head>
         <body>

In most cases, it is best to leave the Fossil-generated HTML Header
alone. (One exception is when the administrator needs to include links
to additional CSS files.) The configurable part of the skin begins
with the Content Header section which should follow this template:

        <div class="header">
          ... top banner and menu bar ...
        </div>

Note that `<div class="header">` and `</div>` tags must be included in
the Content Header text of the skin.  In other words, you, the
administrator, need to supply that text as part of your skin
customization.

The Fossil-generated Content section immediately follows the Content Header.
The Content section will looks like this:

        <div class="content">
          ... Fossil-generated content here ...
        </div>

After the Content is the custom Content Footer section which should
follow this template:

        <div class="footer">
          ... skin-specific stuff here ...
        </div>
        <script nonce="$nonce">
          <th1>styleScript</th1>
        </script>
