        - automatic decompression of zip (cbz),  rar  (cbr),  ace  (cba),  targzipped  (cbg)  and
       tarbzip2ped (cbb) archives

        - rar/unrar (one of them), unzip, unace and tar (with gzip and bzip2 support compiled-in)
       available somewhere in the PATH (e.g. in /usr/bin). If one of them is missing,  you  won't
       be able to open some archives
        - a lot of disk space available in /tmp directory, for handling decompression of archives



       File menu provies basic operations for loading comic books:
        - Open directory - open directory containg images.
        - Open archive - open archived images.
        -  Recently  opened  -  list of ten recently opened archives / directories (most recently
       opened on the top).
        - Info - displays information about currenly opened comic book. This includes contents of
       file_id.diz *.nf o files (if any) as well as memory usage info.
        - Settings - allows you to fine-tune some options.
        - Close - closes currently opened comic book.
        - Quit - quits QComicBook.

       QComicBook  offers some tunable options, available via Settings menu option. These options
        - Background color - the color of the empty area around displayed image.
        - Hide menubar in fullscreen mode - menubar may be hidded in fullscreen mode if  desired;
       together  with toolbar hiding option, it may give you the whole screen for displaying page

        -  Scaling  method  - the algorithm used for image scaling; either Smooth or Fast. Smooth
       scaling provides best quality, but is slower; it is  recommened  method  unless  you  have
       really slow machine.
        -  Cache size - the number of pages kept in memory. Value of 0 disables caching; 1 has no
       effect on performance; 2 or more may improve your experience. Keep in mind,  that  caching
       may  consume  a lot of memory - for example, an 1280x1984 image may take as much as 9Mb of
        - Preload next page - enables page preloading  in  the  background.  This  setting  takes
       effect  only  for cache size of 3 and greater. It is recommended to enable this option, as
       it may really improve overall experience.
        - Use disk cache for thumbnails - thumbnails are saved to disk, which  speeds  up  things
       when  loading  them  later.  Set  this option on if you tend to open comic books more then
        - Number of days to keep thumbnails - defines, for how long to keep thumbnails  on  disk;
       old thumbnails are deleted when exiting QComicBook. Value of 0 disables purging.

       other external web browser.
        - Forward and backward two pages in two-pages mode.
        - Open info dialog after opening comic book - when enabled, info dialog is  opened  after
       opening comic book. You may still open this dialog manually with File/Info menu option.
        - Confirm exit.

       Note: changing cache size takes effect on new comic book.

       Bookmarks menu allows you to bookmark pages in comic books. These  bookmarks  are  however
       somewhat  different  than,  for  example,  in any webbrowser and are more similiar to real
       bookmarks. Each bookmark keeps bookmarked page number (as well as file name), so  you  can
       easily start with your comic book from the point, where you last stopped reading.

       Two options are available in this menu:
        -  Set  bookmark  for  this comicbook - creates bookmark for current comic book; existing
       bookmark for this comic book is deleted.
        - Remove bookmark for this comicbook - removes existing bookmark for current comic  book;
       to remove other bookmarks, use Manage bookmarks option.
        - Manage bookmarks - opens bookmark manager, where bookmarks can be easily removed.

       Below  these  options you can see the list of currently saved bookmarks. Just click on one
       of them to go to bookmarked comic book and page.

       Here is some information for people interested in QComicBook internals.

       1. Settings handling

       QComicBook keeps settings in ~/.qcomicbook directory within these two files:
        - qcomicbookrc - main configuration file
        - bookmarks - bookmarks file

       Both files are plain text files and may be edited manually (with caution!), if needed.

       2. Thumbnails handling

       Thumbnails  are  stored  (if  thumbnails  disk  caching is enabled) in ~/.qcomicbook/cache

       3. Archives handling

       Archived comic books are decompressed to temporary directory (/tmp/qcomicbook-XXXXX,  with
       XXXXX being some random number). This directory is purged when closing current comic book,
       opening a new one or quitting QComicBook.
