+This is X Transparent Lock.  Xtrlock is a very minimal X display lock
+program, which uses nothing except the Xlib library.  It doesn't
+obscure the screen, it is completely idle while the display is locked
+and you don't type at it, and it doesn't do funny things to the X
+access control lists.  On my system the binary is under 10K
+(Linux/i386, compiled with gcc -O2 -m486 -s).
+
+Note that xtrlock currently does not work with shadow passwords.  If
+someone sends me some portable patches for shadow password support
+I'll probably include them.
+
+[ Shadow passwords are now supported on Linux, and Solaris 2.x (not
+  tested).  To work with shadow passwords, this program should be
+  compiled with -DSHADOW_PWD and installed setuid root (it will drop
+  privileges as soon as possible).  The shadow-aware version will
+  still work fine if you don't have shadow passwords.
+
+  April 9, 1996
+  -- Marek Michalkiewicz <[email protected]> ]
+
+You need an ANSI C compiler, such as GCC.  Do not attempt to compile
+xtrlock with an old C compiler such as most systems' `cc'.
+
+There is no support for X resources or command-line arguments - the
+timeouts and cursor bitmaps and colours cannot be modified.  If
+someone sends me some Xlib-only X resource support I may include it.
+
+To install xtrlock:
+
+Build the program:
+	xmkmf
+	make
+
+Test it:
+	./xtrlock
+
+Install it and the manpage:
+	really make install install.man

+
+This package was put together by Stephen Early
+<[email protected]>, from the source by Ian Jackson, which he
+obtained from Usenet.  Apart from a couple of bugfixes the changes
+were very minimal - merely adding support for the Debian package
+maintenance scheme, by adding various debian.* files.
