- NOTE: Although vfs has been meant to be implemented as a separate
- entity redistributable under the LGPL in its current implementation it
- uses GPLed code from src/. So there are two possibilities if you want
- to use vfs:
- 1. Distribute your copy of vfs under the GPL. Then you can freely
- include the GPLed functions from the rest of the mc source code.
- 2. Distribute your copy of vfs under the LGPL. Then you cannot include
- the functions outside the vfs subdirectory. You must then either
- rewrite them or work around them in other ways.

- Hi!
- I'm midnight commander's vfs layer. Before you start hacking me,
- please read this file. I'm integral part of midnight commander, but I
- try to go out and live my life myself as a shared library, too. That
- means that I should try to use as little functions from midnight as
- possible (so I'm tiny, nice and people like me), that I should not
- pollute name space by unnecessary symbols (so I do not crash fellow
- programs) and that I should have a clean interface between myself and
- midnight.
- Because I'm rather close to midnight, try to:
- * Keep the indentation as the rest of the code. Following could help
- you with your friend emacs:
- (defun mc-c-mode ()
- "C mode with adjusted defaults for use with the Midnight commander."
- (interactive)
- (c-mode)
- (c-set-style "K&R")
- (setq c-indent-level 4
- c-continued-statement-offset 4
- c-brace-offset 0
- c-argdecl-indent 4
- c-label-offset -4
- c-brace-imaginary-offset 0
- c-continued-brace-offset 0
- c-tab-always-indent nil
- c-basic-offset 4
- tab-width 8
- comment-column 60))
- (setq auto-mode-alist (cons '(".*/mc/.*\\.[ch]$" . mc-c-mode)
- auto-mode-alist))
- And because I'm trying to live life on my own as libvfs.so, try to:
- * Make sure all exported symbols are defined in vfs.h and begin with
- 'vfs_'.
- * Do not make any references from midnight into modules like tar. It
- would probably pollute name space and midnight would depend on concrete
- configuration of libvfs. mc_setctl() and mc_ctl() are your
- friends. (And mine too :-).

- PS: If you'd like to use my features in whole operating system, you
- might want to link me to rpc.nfsd. On
- http://atrey.karlin.mff.cuni.cz/~pavel/podfuk/podfuk.html you'll find
- how to do it.
- PPS: I have a friend, shared library called avfs, which is LD_PRELOAD
- capable. You can reach her at http://www.inf.bme.hu/~mszeredi/avfs.
