NAME
     QComicBook - QT viewer for comic book archives (cbr/cbz)

SYNOPSIS
     qcomicbook [archive] [dir] ...

DESCRIPTION
     QComicBook  is a viewer for comic book archives containing jpeg/png/xpm/gif
     images, which aims at convenience and simplicity.

     Features include:
      - automatic decompression of zip (cbz), rar (cbr), ace  (cba),  targzipped
     (cbg) and tarbzip2ped (cbb) archives
      - full-screen mode
      - two-pages viewing
      - page scaling
      - mouse or keyboard navigation
      - bookmarks
      - thumbnails
      - page caching and page preloading
      - ... and more

     QComicBook software requirements:
      -  rar/unrar (one of them), unzip, unace and tar (with gzip and bzip2 sup-
     port 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 decompres-
     sion of archives

MENU
     File

     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  in-
     cludes  contents of file_id.diz *.nf o files (if any) as well as memory us-
     age 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 include:
      - 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 contents.
      - Hide  statusbar  in  fullscreen  mode  -  statusbar  may  be  hidden  in
     fullscreen mode, giving you even more space.
      - Small mouse cursor - toggles small (4x4 pixels) mouse cursor for QComic-
     Book window.
      -  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 experi-
     ence. Keep in mind, that caching may consume a lot of memory - for example,
     an 1280x1984 image may take as much as 9Mb of memory!
      - Preload next page - enables page preloading in the background. This set-
     ting  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 once.
      - Number of days to keep thumbnails - defines, for how long to keep thumb-
     nails on disk; old thumbnails are deleted when exiting QComicBook. Value of
     0 disables purging.
      - Help browser - allows to choose between simple built-in browser (the de-
     fault) or any 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.

     View

     View submenu provides some basic settings for page view.

     You can select one of the following scaling modes:
      - Original size - no scaling is done and original image size is preserved.
      - Fit width - image is scaled to fit window width.
      - Fit height - image is scaled to fit window height.
      - Whole page - image is scaled to fit window.
      - Best fit - depending on image dimensions, QComicBook  chooses  the  best
     method to scale image.

     The page can be rotated with 90 degree step, with these options:
      - Rotate right - rotates image clockwise.
      - Rotate left - rotates image counter clockwise.
      - No rotation - resets rotation, restores original image.
      - Preserve rotation - makes rotation "permanent" for viewing next pages.

     Other options in this menu:
      - Fullscreen - toggles beetween fullscreen and windowed mode; please note,
     that  depending  on you settings, menubar may be hidden in fullscreen mode,
     so to back to windowed mode you need to press F11 or ESC key.
      - Two pages - display two pages, side by side, just like when reading nor-
     mal book.
      - Japanese mode - scrolls to top-right corner on page change; in two pages
     mode additionaly swaps pages.
      - Thumbnails - toggles thumbnails window.
      - Scrollbars - toggles displaying of scrollbars for  large  pages;  please
     note that scrollbars will be shown only if necessary.
      - Toolbar - toggles displaying of toolbar.
      - Statusbar - toggles displaying of statusbar.

     Settings  in  this  menu  are  saved  when  quitting QComicBook (except for
     "fullscreen" option).

     Bookmarks

     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  cur-
     rent 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.

INTERNALS
     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 ~/.qcomic-
     book/cache directory.

     3. Archives handling

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