+The main goal is to provide a faster way to explore a file system from
+the terminal, compared to what's possible by using `cd`, `ls`, etc. fm
+has vi-like key bindings for navigation and can open files in $PAGER and
+$EDITOR. Basic file system operations are also implemented (see fm(1)
+for details). fm is designed to be simple, fast and portable.

Quick Start
===========
Running:
```
- $ rover [DIR1 [DIR2 [DIR3 [...]]]]
+ $ fm [DIR1 [DIR2 [DIR3 [...]]]]
```
Basic Usage:
```
- q - quit Rover
- ? - show Rover manual
+ q - quit fm
+ ? - show fm manual
j/k - move cursor down/up
J/K - move cursor down/up 10 lines
g/G - move cursor to top/bottom of listing
D - delete selected file or (empty) directory
```
- Please read rover(1) for more information.

Requirements
Configuration
=============
- Rover configuration (mostly key bindings and colors) can only be changed by
+fm configuration (mostly key bindings and colors) can only be changed by
editing the file `config.h` and rebuilding the binary.
- Note that the external programs executed by some Rover commands may be changed
-via the appropriate environment variables. For example, to specify an editor:
- ```
- $ VISUAL=vi rover
- ```
+Note that the external programs executed by some fm commands may be
+changed via the appropriate environment variables. For example, to
+specify an editor:
- Rover will first check for variables prefixed with ROVER_. This can be used to
-change Rover behavior without interfering with the global environment:
- ```
- $ ROVER_VISUAL=vi rover
- ```
+```
+$ VISUAL=vi fm
+```

-print help message and exit
-.TP
-\fB\-v\fR, \fB\-\-version\fR
-print program version and exit
-.SH CONCEPTS
-.SS TABS
-.PP
-Rover is operated via a tabbed interface. There are always ten tabs in total,
-numbered from 0 to 9. At any given moment, one (and only one) tab is visible on
-the screen. The number of the tab currently visible is shown on the top right
-corner of the screen. To view a different tab, one just needs to press its
-corresponding number. Each tab has a \fBcurrent working directory\fR (\fBCWD\fR)
-associated to it, also shown on the top of the screen. The \fBCWD\fR of the
-visible tab is changed as the user navigates through the file system.
-.PP
-It's also possible to set the \fBCWD\fR of tabs at Rover start-up by passing the
-desired paths as command-line arguments. The tab number 0 always starts at
-\fB$HOME\fR. If more than nine directories are specified, only the first nine
-are used for tabs 1\-9 and the rest are ignored. Tabs for which an invalid path
-was assigned will also start at \fB$HOME\fR. Remaining tabs not specified on
-the command line start at the current working directory of the parent process.
-.SS ENTRIES
-.PP
-An \fBentry\fR is anything that may be found inside a directory in some file
-system. It may be a file, a directory, a link, a socket, a FIFO, etc. In its
-most basic usage, Rover will gather a list of entries inside the \fBCWD\fR
-and present it on the screen.
-.PP
-There is always one (and only one) highlighted entry visible. This is both the
-\fBcursor\fR location and the current \fBselection\fR. The highlighting moves as
-the user navigates the entry list with cursor commands. Simple operations, like
-entering a subdirectory or renaming a file, are done by first selecting the
-relevant entry and then issuing the appropriate command (see the \fBCOMMANDS\fR
-section). For commands that operate on more than one entry at once (batch
-commands), selection is not sufficient, since it's not possible to select more
-than one entry. Batch commands are performed on marked entries.
-.SS MARKS
-.PP
-For some file operations, it is convenient to first \fBmark\fR all entries that
-are to be processed, so that the appropriate command only needs to be issued
-once. For such purpose, Rover allows an arbitrary number of entries to be
-marked, with the limitation that they must be all in the same directory.
-.PP
-Unlike simple selection, the effect of marks is not constrained by visibility.
-This is so one can mark a number of entries in some directory, navigate to another
-directory, and then finally issue a copy or move command. Moreover, marks are
-shared over all tabs. This allows one to mark some entries in one tab that is
-pointed to the "source" directory of the operation and then issue the command on
-another tab that is pointed to the "destination" directory.

-.TP

-.SH LINE EDITING
-.PP
-Some commands will prompt for an input string. For example, in order to rename a
-file, the user must supply the new name. This string will appear at the bottom
-of the screen and must be edited interactively using the keyboard. Printable
-keys will insert characters at the cursor position. The following shortcuts are
-available for line editing:
-.TP
-.B <TAB>
-Finish editing and \fBcancel\fR command.
-.TP
-.B <RETURN>
-Finish editing and \fBconfirm\fR command.
-.TP
-.B <LEFT>/<RIGHT>
-Move insertion cursor left/right.
-.TP

-.TP
-.B <BACKSPACE>
-Remove one character before cursor.
-.TP
-.B <DELETE>

-.TP
-.B SHELL
-Name of shell program (e.g. \fI/bin/sh\fP).
-.TP
-.B PAGER
-Name of pager program (e.g. \fIless\fP).
-.TP
-.B VISUAL
-Name of visual editor program (e.g. \fIvim\fP or \fIemacs\fP).

-.B EDITOR
-Name of line editor program (e.g. \fIed\fP or \fIex\fP).
-.TP
-.B CLIP
-Path of clipboard file (e.g. \fI/tmp/clipboard\fP).
-The user must have read and write permissions on this path.
-If this variable is not defined, Rover will use an internal, in-memory, clipboard.
-.TP
-.B RVSEL
-Rover writes the name of the selected entry to this variable before running a
-subprocess. This allows one to use the selection as part of an arbitrary command
-by first invoking a shell from Rover (see the \fBCOMMANDS\fR section) and then
-typing something like \fBgrep abc "$RVSEL"\fR.
-.TP
-.B OPEN
-This variable can be set to a command accepting a single argument: a filename.
-The command is supposed to open the given file with an appropriate program.
-.TP
-.B ROVER_SHELL, ROVER_PAGER, ROVER_VISUAL, ROVER_EDITOR, ROVER_OPEN
-If any of these variables are set, they override \fBSHELL\fR, \fBPAGER\fR,
-\fBVISUAL\fR, \fBEDITOR\fR and \fBOPEN\fR, respectively.
-.SH CONFIGURATION
-.PP
-If you want to change Rover key bindings or colors, you can edit the
-\fIconfig.h\fP file in the source distribution and recompile the program. Rover
-will not use or create any external file during its execution, except when asked
-to do so by user commands or command-line options.
-.SH NOTES
-.PP
-\fBImportant\fR: Currently, Rover never asks for confirmation before overwriting
-existing files while copying/moving marked entries. Please be careful to not
-accidentally lose your data.
