- Added support for the linenoise library, which allows line-editing

and path completion when entering filenames for receive- and send-
  file operations. Support can be compiled-out if you wish. See Makefile.

- When entering a filename for receive- or send- file operations, 
  pressing C-c cancels the operation. 
  This works regardless of whether linenoise support (see above) has
  been compiled in or not

- Use debian's xmltoman to convert manual page form xml to man.

+# Linenoise
+
+A minimal, zero-config, BSD licensed, readline replacement used in Redis,
+MongoDB, and Android.
+
+* Single and multi line editing mode with the usual key bindings implemented.
+* History handling.
+* Completion.
+* About 1,100 lines of BSD license source code.
+* Only uses a subset of VT100 escapes (ANSI.SYS compatible).
+
+## Can a line editing library be 20k lines of code?
+
+Line editing with some support for history is a really important feature for command line utilities. Instead of retyping almost the same stuff again and again it's just much better to hit the up arrow and edit on syntax errors, or in order to try a slightly different command. But apparently code dealing with terminals is some sort of Black Magic: readline is 30k lines of code, libedit 20k. Is it reasonable to link small utilities to huge libraries just to get a minimal support for line editing?
+
+So what usually happens is either:
+
+ * Large programs with configure scripts disabling line editing if readline is not present in the system, or not supporting it at all since readline is GPL licensed and libedit (the BSD clone) is not as known and available as readline is (Real world example of this problem: Tclsh).
+ * Smaller programs not using a configure script not supporting line editing at all (A problem we had with Redis-cli for instance).
+ 
+The result is a pollution of binaries without line editing support.
+
+So I spent more or less two hours doing a reality check resulting in this little library: is it *really* needed for a line editing library to be 20k lines of code? Apparently not, it is possibe to get a very small, zero configuration, trivial to embed library, that solves the problem. Smaller programs will just include this, supporing line editing out of the box. Larger programs may use this little library or just checking with configure if readline/libedit is available and resorting to linenoise if not.
+
+## Terminals, in 2010.
+
+Apparently almost every terminal you can happen to use today has some kind of support for basic VT100 escape sequences. So I tried to write a lib using just very basic VT100 features. The resulting library appears to work everywhere I tried to use it, and now can work even on ANSI.SYS compatible terminals, since no
+VT220 specific sequences are used anymore.
+
+The library is currently about 1100 lines of code. In order to use it in your project just look at the *example.c* file in the source distribution, it is trivial. Linenoise is BSD code, so you can use both in free software and commercial software.
+
+## Tested with...
+
+ * Linux text only console ($TERM = linux)
+ * Linux KDE terminal application ($TERM = xterm)
+ * Linux xterm ($TERM = xterm)
+ * Linux Buildroot ($TERM = vt100)
+ * Mac OS X iTerm ($TERM = xterm)
+ * Mac OS X default Terminal.app ($TERM = xterm)
+ * OpenBSD 4.5 through an OSX Terminal.app ($TERM = screen)
+ * IBM AIX 6.1
+ * FreeBSD xterm ($TERM = xterm)
+ * ANSI.SYS
+
+Please test it everywhere you can and report back!
+
+## Let's push this forward!
+
+Patches should be provided in the respect of linenoise sensibility for small
+easy to understand code.
