-+ VIM REFERENCE MANUAL by Bram Moolenaar
-+
-+
-+The VIM-Shell *vimshell*
-+
-+1. What is VIM-Shell?
-+
-+The VIM-shell is a extension for VIM, a very popular programmer's editor for
-+many platforms, written by Bram Moolenaar et al. VIM features split windows,
-+and this patch makes it possible to start shells in those windows. It is only
-+available for POSIX systems like Linux, FreeBSD, OpenBSD, NetBSD and MacOS X.
-+I don't think the Windows-VIM needs such a patch, because I think the command
-+line there isn't really popular.
-+
-+==============================================================================
-+2. How to use the VIM-Shell
-+
-+2.1 General concept: ":vimshell"
-+
-+The whole VIM-Shell functionality is hidden behind one single command:
-+:vimshell.
-+
-+:vimshell[!] [params] tries to close your active buffer and creates a new one.
-+This behaves exactly the same as the :enew command (see :help enew im VIM for
-+details). If you have local modifications to your buffer, the command will be
-+aborted (but you can override this by adding a ! at the end, in this case the
-+active buffer will be dismissed in any case). The window containing this empty
-+buffer is then converted to a VIM-Shell.
-+
-+:vimshell
-+
-+starts a VIM-Shell in your current window. I strongly suggest you open a new
-+window before doing that. By default, without any parameters, /bin/sh will be
-+spawned.
-+
-+:vimshell bash
-+
-+When called with parameters, VIM-Shell passes these parameters verbatim to
-+execvp when starting a shell. Your current $PATH will be searched for the
-+command.
-+
-+:vimshell irssi -n anonymous -c vienna.irc.at
-+
-+starts the textmode IRC client "irssi" with the abovementioned parameters.
-+
-+:vimshell mutt
-+
-+Never lose track of your e-mails while working in VIM!
-+
-+When you exit such a shell, or the program running in it terminates, the
-+buffer will be converted back to a normal, empty VIM-buffer. The window will
-+not be closed.
-+
-+2.2 Navigation
-+
-+When the currently active window is a VIM-Shell, every character entered gets
-+routed to the shell, and no mapping expansion takes place. VIM doesn't get any
-+notice of the characters that you type in a VIM-Shell.
-+
-+The big exception is Ctrl_W, which is passed through to VIM, so you can close
-+the VIM-shell (Ctrl_W + c), change to another window, resize the window, etc.
-+Key mappings
-+
-+Because I feel that opening up a window and then typing :vimshell is a bit
-+cumbersome, I suggest you use the following key mappings in your .vimrc:
-+
-+ " VIM-Shell
-+ " Ctrl_W e opens up a vimshell in a horizontally split window
-+ " Ctrl_W E opens up a vimshell in a vertically split window
-+ " The shell window will be auto closed after termination
-+ nmap <C-W>e :new \| vimshell bash<CR>
-+ nmap <C-W>E :vnew \| vimshell bash<CR>
-+
-+Just hitting Ctrl_W and e to drop a shell window in your VIM session is
-+really, really comfortable :-)
-+
-+This is a small introduction on how to use the new features in your
-+VIM-Shell-enabled VIM.
