          smugfs - file system access to SmugMug photo sharing

          smugfs [ -DFH ] [ -k keypattern ] [ -m mtpt ] [ -s srvname ]

          Smugfs is a user-level file system that provides access to
          images stored on the SmugMug photo sharing service.  It logs
          in after obtaining a password from factotum(4) using
 and keypattern (if any) as key criteria
          (see auth(3)). Then smugfs serves a virtual directory tree
          mounted at mtpt (default /n/smug) and posted at srvname , if
          the -s option is given.

          The directory tree is arranged in five levels: root, user,
          category, album, and image.  For example, /n/smug/cmac/ is a
          user directory, /n/smug/cmac/People/ is a category direc-
          tory, /n/smug/cmac/People/Friends/ is an album directory,
          and /n/smug/cmac/albums/Friends/2631/ is an image directory.

          SmugMug allows fine-grained classification via subcate-
          gories, but subcategories are not yet implemented.

          All directories contain a special control file named ctl;
          text commands written to ctl change smugfs's behavior or
          implement functionality that does not fit nicely into the
          file system interface.

          Smugfs caches information about users, categories, albums,
          and images.  If changes are made outside of smugfs (for
          example, using a web browser), the cache may need to be dis-
          carded.  Writing the string sync to a directory's ctl file
          causes smugfs to discard all cached information used to pre-
          sent that directory and its children.  Thus, writing sync to
          the root ctl file discards all of smugfs 's cached informa-

        Root directory
          The root directory contains directories named after users.
          By default, it contains only a directory for the logged-in
          user, but other directories will be created as needed to
          satisfy directory lookups.

          In addition to user directories, the root directory contains
          three special files: ctl, rpclog, and uploads.  Reading
          rpclog returns a list of recent RPCs issued to the SmugMug
          API server.  Reads at the end of the file block until a new
          RPC is issued.  The uploads file lists the file upload queue

        User directories
          User directories contain category directories named after
          the categories.  SmugMug pre-defines a variety of cate-
          gories, so it is common to have many categories that do not
          contain albums.

          In a user directory, creating a new directory creates a new
          category on SmugMug.  Similarly, renaming or removing a cat-
          egory directory renames or removes the category on SmugMug.
          Categories cannot be removed if they contain albums.

          User directories also contain a directory named albums that
          itself contains all of that user's albums.

        Category directories
          Each category directory contains album directories named
          using the album's title.

          In a category directory, creating a new directory creates a
          new album on SmugMug.  Similarly, renaming or removing an
          album directory renames or removes the album on SmugMug.
          Albums cannot be removed if they contain images.

        Album directories
          Each album directory contains image directories named using
          the image's decimal SmugMug ID.  Image directories cannot be
          created or renamed, but they can be removed.  Removing an
          image directory removes the image from the album on SmugMug.

          Album directories also contain three special files, ctl,
          settings, and url.

          The settings file contains the album settings in textual
          form, one setting per line.  Each line represents a single
          setting and is formatted as an alphabetic setting name fol-
          lowed by a single tab followed by the value.  Many settings
          can be changed by writing new setting lines, in the same
          format, to the settings file.

          Copying a file into the album directory queues it for
          uploading to SmugMug to be added to the album.  Files disap-
          pear from the album directory once they have finished
          uploading, replaced by new image directories.  The uploads
          file in the root directory lists all pending uploads, which
          are stored temporarily in /var/tmp.

        Image directories
          Each image directory contains an image file, named with its
          original name, if available.  If the image belongs to
          another user, SmugMug does not expose the original name, so
          the file is named nnnn.jpg, where nnnn is the SmugMug image
          ID number.  The file content is the original image or else

          the largest image available.

          The directory contains a settings file holding per-image
          settings, similar to the file in the album directory; and a
          url file, containing URLs to the various sized images on the
          SmugMug server.

          Mount smugfs on /n/smug; the current user must have write
          access to /n/smug and /dev/fuse.

               % smugfs
               Watch API calls as they execute:

               % cat /n/smug/rpclog &
               Create a new album in the Vacation category and fill it
               with photos:

               % mkdir /n/smug/you/Vacation/Summer
               % cp *.jpg /n/smug/you/Vacation/Summer

          The photos are now uploading in the background.  Wait for
          the uploads to finish:

               % while(test -s /n/smug/uploads) sleep 60

          Make the album publicly viewable and share it.

               % echo public 1 >/n/smug/you/Vacation/Summer/settings
               % cat /n/smug/you/Vacation/Summer/url | mail friends



          If multiple categories or albums have the same name, only
          one will be accessible via the file system interface.
          Renaming the accessible one via mv(1) will resolve the prob-

          Boolean values appear as true and false in settings files
          but must be changed using 1 and 0.
