NAME
       gentoo - a fully GUI-configurable X file manager using GTK+

SYNOPSIS
       gentoo [--version] [--root-ok] [--no-rc] [--no-gtkrc] [--left=path]
       [--right=path]

DESCRIPTION
       gentoo is a file manager for Linux and compatible systems. It allows
       you to interactively navigate your file system using the mouse, and
       also to perform various fairly standard operations (such as copy, move,
       rename, ...)  on the files and directories contained therein.

       gentoo always shows you the contents of two directories at once. Each
       of these is displayed in its own scrollable list, called a pane. At any
       time, exactly one pane is the current pane, and has a highlighted bar
       running across its top region. The current pane acts as the source for
       all file operations, while the other pane is the destination. You can
       select rows in panes using selection methods of varying complexity
       (from simply clicking a row, to selecting rows by name using a regular
       expression). Once you have a selection, you can click a button to
       perform some command on the selected files.

       All file operations performed by gentoo are implemented natively. When
       you use gentoo to copy a file, for example, gentoo does not simply
       execute the system's cp(1L) command. Rather, gentoo contains its own
       code for opening source and destination files, and then reading and
       writing the right amount of data between them. This way of doing things
       makes gentoo independant of the availability of shell commands to do
       things.

       gentoo incorporates a fairly powerful, object-oriented file typing and
       styling system. It can use a variety of ways to determine the type of
       the files it is displaying. Each type is then linked to something
       called a style, which controls how rows of that type are rendered in
       panes. You can use this system to control icons, colors, and various
       operations on the rows. For example, it is easy to make gentoo display
       all PNG images in red, and to invoke The GIMP(1) on them when double-
       clicked.

       A design goal with gentoo has been to provide full GUI configurability,
       removing the need to edit a config file by hand and restart the program
       to see the changes, as is otherwise common in many programs for Un*x.
       As a result of this, gentoo features a Configuration dialog window
       where you can configure most aspects of its operation directly, using
       the mouse and standard GUI widgets.

       gentoo borrows its basic look'n'feel from the classic Amiga file
       manager Directory OPUS.

OPTIONS
       gentoo is not primarily driven by command line arguments, but the
       following are available:

       --version
              Causes gentoo to print its version number (a string on the form
              MAJOR.MINOR.MICRO, like 0.11.24) to the standard output, and
              then exit successfully. Numbers having an odd MINOR component
              indicate development versions of the program.

       --root-ok
              Makes gentoo accept being run by the root user. Normally, this
              is not allowed since it is considered a big threat to system
              security. Note that gentoo has the ability to execute user-
              defined strings using the execvp(3) function. This is generally
              considered harmful. However, if you really want to run gentoo
              while logged on as root, supplying this option allows you to. It
              is not recommended, though.

       --no-rc
              Starts up gentoo without loading any configuration file. This
              makes it run using the built-in defaults, which are very Spartan
              indeed. Seldom comfortable.

       --no-gtkrc
              Avoids loading the GTK+ RC file, thus disabling any widget
              customizations, and forces all widgets to use the default GTK+
              look.

       --left, --right
              Sets the initial path for the left and right pane, respectively.
              If present, the path specified with one of these options
              overrides any other path for the pane in question. See below
              (Initial Directory Paths) for details.

       Any non-option command arguments will be silently ignored. If an
       argument "-h" or "--help" is given, gentoo will give a summary of its
       supported command line options and exit successfully. If an unknown
       option is given, or a option is missing a required argument, gentoo
       will whine and exit with a failure.

BASIC USAGE
       When gentoo starts up, it will open up its single main window, which is
       split vertically down the middle, forming the two panes mentioned
       above. It also contains a bank of buttons along the bottom.

   Initial Directory Paths
       The actual paths shown in the two panes upon start-up can be controlled
       in various ways. There are four ways of getting a path to show up in
       pane. In order of decreasing priority, they are:

       1. Command-line Argument
              Using the --left and --right (or their short forms, -1 and -2)
              command-line arguments overrides any other setting.

       2. Configured Default Directory
              If no command-line argument is present, and the "Default
              Directory" configuration option is set, that directory is used.

       3. Most Recently Visited Directory
              If no default directory exists, the most recently visited
              directory is taken from the directory history for each pane.
              This only works if a directory history file has been found and
              loaded.

       4. Current Directory
              If all else fails, gentoo uses the current directory (".").

   Navigating
       Navigating around the file system using gentoo is very simple. The two
       panes act as independent views of the file system, and are navigated in
       exactly the same way.

       You can always see which directory a pane is showing by reading its
       path, shown in the entry box below (by default--you can change the
       position to above) the pane.

       To enter a directory, locate it in the pane and double click it with
       the left mouse button. gentoo will read the directory's contents, and
       update the display accordingly.

       There are several ways of going up in the directory structure. To enter
       the directory containing the one currently shown (the current dir's
       parent), you can: click the parent button (to the left of the path
       entry box); hit Backspace on your keyboard; click the middle mouse
       button; select "Parent" from the pop-up menu on the right mouse button,
       or click the downward arrow to the right of the path box (this pops up
       the directory history menu), then select the second row from the top.

   Selecting Files
       Before you can do anything to a file, you need to select it. All file-
       management commands in gentoo act upon the current selection (in the
       current pane). There are several ways of selecting files, but the most
       frequently used are mouse-based. Note that the word "file" used below
       really should be taken to mean "file or directory", since selection
       doesn't distinguish between the two.

       To select a file (or directory), just point the mouse at the name
       (anywhere in the row is fine), and click the left mouse button. The
       colors of the clicked row will change, indicating that it is currently
       selected. To select more rows, keep the mouse button down, and drag the
       mouse vertically. gentoo extends the selection, including all rows
       touched.  If you drag across the top or bottom border, the pane will
       scroll, trying to keep up.  This is a very quick and convenient way of
       selecting multiple files, as long as they are listed in succession.

       If you click again on an already selected file, you will deselect it.
       You can drag to deselect several files, just as when selecting.

       To select a sequence of files without dragging, first click normally on
       the first file that you wish to select. Then release the mouse button,
       locate the last file in the sequence (it can be either above or below
       the first one), hold down shift on your keyboard, and click the wanted
       file. gentoo now adds all files between the first and the last to the
       current selection.

       If you follow the instructions given above to select a sequence, but
       press control rather than shift before clicking the second time, gentoo
       will deselect the range of files indicated.

       If you click on a file with the meta key held down (that's actually a
       key labeled Alt, located to the immediate left of the space bar, on my
       PC keyboard), gentoo will do something cool: it will select (or
       deselect, it's a toggle just like ordinary selection) all files,
       including the clicked one, that have the same type as the one you
       clicked. This can be used to select for example all PNG image files in
       a directory even if you can only see one. Occasionally very useful.

       If you click on a file with both the shift and control keys held down,
       gentoo will toggle the selected state of all files having the same file
       name extension as the one you clicked. This can sometimes be useful to
       select files that you don't have a proper type defined for, as long as
       those files do share an extension, that is.

   Changing Sort Order
       The files and directories listed in each of gentoo's two panes are
       always sorted on some column: typically file name. You can chose to
       sort on some other field by clicking the appropriate column title once.
       If you click on the field that is already current, the sorting will be
       reversed (i.e., for names it will be Z-A rather than A-Z).

       If your display includes icons, try sorting on that column: gentoo will
       then order each row according to its File Style, grouping the rows
       based on their parent styles, all the way up to the root of the Style
       tree. This means that, for example, JPEG and PNG pictures (both having
       an immediate parent style of Image) will be shown together, and before
       all Text files (HTML, man pages and so on). It's quite cool, really. :)

   Executing Commands
       Commands are used to make gentoo do stuff. The typical command operates
       upon the set of selected files in the current pane, so it's usually a
       good idea to first select some files. See the previous subsection for
       details on how to select files. Once you have a bunch of files
       selected, you need to tell gentoo which command to execute. There are
       several ways of doing this.

       Most basic file operations (e.g. copy, move, rename, and so on) are
       found on the (cleverly labeled) buttons along the bottom of gentoo's
       main window. To copy a file, just select it, then click the button
       labeled "Copy". It's really that simple. Most of these built-in (or
       native) commands automatically operate recursively on directories, so
       you could copy (or move) a whole directory of files by just selecting
       it and then clicking "Copy".

       If you can't see a button that does what you want to do, there's a
       chance that the command exists, but isn't bound. Click the right mouse
       button in a pane, this opens up the "pane pop-up menu". Select the
       "Run..." item. This opens up a dialog window showing all available
       commands. Select a command, and click "OK" to execute it.

CONFIGURATION
       gentoo is a pretty complicated program; it has a rather large amount of
       configuration data that it needs in order to be really useful. For
       example, my current personal configuration file contains well over a
       thousand different configuration values.

       To store this hefty amount of config data, gentoo uses a heavily
       structured config file. In fact, the file is (or at least it should be)
       legal XML!

       When new features are added to gentoo, they will typically require some
       form of configuration data. This data is then simply added somewhere in
       the existing config file structure. Effort is made to assign reasonable
       built-in default values for all such new features, so older
       configuration files (that don't contain the values required by the new
       features) should still work. The first time you hit "Save" in the
       configuration window after changing your version of gentoo, your
       personal config file will be updated to match the version of gentoo.

       Describing how to go about configuring gentoo is too big a topic for a
       manual page to cover. I'll just say that the command to open up the
       configuration window is called "Configure". It is by default available
       on a button (typically the top-right one), in the pane pop-up menu, and
       also by pressing the C key on your keyboard.

FILES
       ~/.gentoorc
              A user's personal configuration file. When gentoo starts up, it
              will try to load this file. If the file isn't found, the site-
              wide configuration will be tried instead.

       /usr/local/etc/gentoorc
              This is the site-wide configuration file. If a user doesn't have
              a config in his/her home directory, gentoo loads this file
              instead. The actual location of this file is slightly system-
              dependent, the above is the default. As an end user, you
              typically won't need to access this file manually.

       ~/.gentoo-history
              This file contains lists of the most recently visited
              directories, for both panes. These are the lists that appear in
              the drop-down menu when the arrow next to the path entry box is
              clicked. Can be disabled in the Dir Pane config.

       ~/.gentoogtkrc
              This file allows you to control the look of the widgets used by
              gentoo, through the GTK+ style system. This file must be present
              in the user's home directory - there is no site-wide GTK+
              configuration file.

       /etc/passwd, /etc/group
              These two files normally hold the system's password and group
              information.  These are (probably) the ones gentoo uses to map
              user IDs to login names, to do tilde-expansion (mapping of user
              name to directory path), and to map group IDs to group names.
              That is probably, because gentoo doesn't actually refer to these
              files by name. Instead, it uses the (BSD-style) API function
              calls getpwent(3) and getgrent(3) to access this information.

       /etc/fstab, /proc/mounts, (or /etc/mtab)
              These files contain data on available and mounted file systems.
              They are read by gentoo's automounting code. You can configure
              the exact file names used, on the "Mounting" tab in the main
              configuration window.  Note that using /proc/mounts rather than
              /etc/mtab is recommended on Linux systems; they contain roughly
              the same data, but the one in /proc is always up to date, and
              faster to read!


BUGS
       All releases of gentoo numbered 0.x.y, where x (the so called minor
       version number) is odd, are to be considered development releases, as
       opposed to stable ones. This means that the software will probably
       suffer from bugs. If you find something that you suspect is indeed a
       bug, please don't hesitate to contact the author!  For details on how
       to do this, see below.

       If you're concerned about using potentially buggy and completely
       unwarranted software to manage your precious files, please feel free
       not to use gentoo. The world is full of alternatives.

       The chances that a bug gets fixed increase greatly if you report it.
       When reporting a bug, you must describe how to reproduce it, and also
       try to be as detailed and precise as possible in your description of
       the actual bug. If possible, perhaps you should include the output of
       gdb(1) (or whatever your system's debugger is called). In some cases it
       might be helpful if you include the configuration file you were using
       when the problem occurred. Before reporting a bug, please make sure
       that you are running a reasonably recent version of the software, since
       otherwise "your" bug might already been fixed. See below for how to
       obtain new releases.

       Also, you should locate and read through the BUGS file distributed with
       gentoo, so you don't go through all this hassle just to report an
       already known bug, thereby wasting everybody's time...

AUTHOR
       gentoo was written, from scratch, by Emil Brink. The first line of code
       was written on May 15th, 1998. It is my first program to use the GTK+
       GUI toolkit, my first program to be released under the GPL, and also my
       first really major Linux application. However, it is not my first
       program! ;^) I've been writing (increasingly complex) code for more
       than a decade. I am currently a computer science student at the Royal
       Institute of Technology (KTH) in Stockholm, Sweden.

       The only efficient way to contact me (to report bugs, give praise,
       suggest features/fixes/extensions/whatever) is by Internet e-mail. My
       address is <emil@obsession.se>.  Please try and include the word
       "gentoo" in the Subject part of your e-mail, to help me organize my
       inbox. Thanks.

ACKNOWLEDGMENTS
       The author wishes to thank the following people for their various
       contributions to gentoo:

       Johan Hanson (<johan@tiq.com>)
              Johan is the man behind all icon graphics in gentoo, and also
              the author of the custom widgets used in it. He also comes up
              with plenty of ideas for new features and changes to old ones,
              some of which are even implemented. Johan has stuff at
              <http://www.bahnhof.se/~misagon/>.

       Jonas Minnberg (<sasq@nightmode.org>)
              Jonas did intensive testing of early versions of gentoo, and
              eventually persuaded me into releasing it (back around version
              0.9.7 or so).

       Ulf Petterson (<ulf@obsession.se>)
              Ulf drew the main gentoo logo (the one shown in the About
              window), and also designed the main HTML documentation's layout.

       Josip Rodin (<jrodin@jagor.srce.hr>)
              Maintainer of the gentoo package for Debian Linux, and also a
              source of suggestions for improvements, as well as a relay for
              bug reports from Debian Linux users.

       Ryan Weaver (<ryanw@infohwy.com>)
              Maintainer of the gentoo packages for Red Hat Linux, and
              probably one of the fastest package creators out there. :)

       Thanks also to all people who have mailed me about gentoo, providing
       bug reports, feature requests, and the occasional kind word. :^) It's
       because of people like yourselves that we have this wonderful computer
       platform to play with.

OTHER INFO
       Some unfinished, outdated, but still pretty informative documentation
       is available, in HTML format, in the docs/ subdirectory in the

       .tar.gz distribution archive, you might need to either inspect the
       distribution you did use (perhaps it came as some form of "package"),
       or contact a system administrator.

       The GTK+ GUI toolkit that gentoo requires is available at
       <http://www.gtk.org>.  gentoo will typically be written to run against
       the latest available stable version of the GTK+ toolkit, and will
       likely not work with the development releases of it.

       The latest version of gentoo is always available on the official gentoo
       home page, at <http://www.obsession.se/gentoo/>.
