+Wed, 26 Jan 00 Geert Jansen <g.t.jansen@stud.tue.nl>
+
+ * Build sycoca for target process.
+ * Use standard debug facilities.
+ * Use KCmdLineArgs for argument parsing.
+ * Dialog updated to use KDialogBase.
+
+Sat, 18 Dec 99 Geert Jansen <g.t.jansen@stud.tue.nl>
+
+ * Add DCOP authentication cookies.
+ * Fixed SMP install of tdesud.
+
+Sat, 23 Oct 99 Geert Jansen <g.t.jansen@stud.tue.nl>
+
+ * STL -> QTL
+ * Use Qt's standard debug facilities.
+
+Tue, 28 Sep 99 Geert Jansen <g.t.jansen@stud.tue.nl>
+
+ * Integrating tdesu into kdebase
+
+Sat, 25 Sep 99 Geert Jansen <g.t.jansen@stud.tue.nl>
+
+ * BIG change: su to other user than root. This required a different way
+ to pass X cookies and stuff to the target process. See
+ common/tdesu_stub.c for more info.
+ * Fixed a bug in tdesud/lexer.cpp
+
+Thu, 23 Sep 99 Geert Jansen <g.t.jansen@stud.tue.nl>
+
+ * Portability issues (root has a csh on FreeBSD ... is this just me?)
+ * The execution of processes is more efficient now: 2 processess instead
+ of 3 and 1 tempfile instead of 2. This way possible by setting the
+ XAUTHORITY env. var. to $HOME/.Xauthority instead of making a new one.
+ * Fixed a subtle bug in tdesud. tdesud catches SIGCHLD to handle child
+ exits but this is incompatible with "class RootProcess", which does a
+ waitpid() and depends on getting the exit code.
+ * Only connect to daemon when necessary.
+
+Wed, 22 Sep 99 Geert Jansen <g.t.jansen@stud.tue.nl>
+
+ * Changed WaitSlave() to open slave instead of master pty.
+ * Added French translation (Pierre Dorgueil).
+ * Updated German translation (Ludwig Nussel).
+ * If su has terminal output, feed it back to the user.
+
+Wed, 8 Sep 99 Geert Jansen <g.t.jansen@stud.tue.nl>
+
+ * If started as root, tdesu does not ask for a password anymore.
+
+Wed, 1 Sep 99 Geert Jansen <g.t.jansen@stud.tue.nl>
+
+ * Deferred instantiation of kapp in tdesu.cpp.
+ * Finished porting to KDE2.
+
+Sun, 29 Aug 99 Geert Jansen <g.t.jansen@stud.tue.nl>
+
+ * Fixed a bug that would let you run only one program with the daemon.
+ * Adapted debug.h macros.
+
+Tue, 24 Aug 99 Geert Jansen <g.t.jansen@stud.tue.nl>
+
+ * Version 0.97
+ * Fixed the RedHat problem! See the function WaitSlave() in
+ common/process.cpp.
+ * Fixed a few GUI bugs.
+ * Improved password security. Passwords are not kept until
+ the root program exits, they are deleted right away.
+
+Fri, 20 Aug 99 Geert Jansen <g.t.jansen@stud.tue.nl>
+
+ * Fixed the glibc 2.1 compile problem (struct ucred test).

+ * Changed behaviour of "Keep Password" setting.
+ * Added -n option: don't offer the choice to keep password.

+ * Source cleanups.
+ * Various small bugfixes.
+ * Merged most of the KDE2 fixes from the CVS version.

+
+Wed, 02 Jun 99 Geert Jansen <g.t.jansen@stud.tue.nl>
+
+ * Version 0.91
+ * The password is passed to su with a pty/tty pair. This should fix the

+Q: On my SuSE system, KDE su does not compile. I get an error that some Qt
+ header files cannot be found.
+A: Install the package qtcompat.
+
+Q: Is KDE su safe?
+A: No program is 100% safe. However, KDE su is not setuid root and it
+ handles the password you enter with great care so it should be safe
+ enough.
+
+Q: How safe is password keeping?
+A: Enabling password keeping is less secure that disabling it. However, the
+ scheme tdesu uses to keep passwords prevents everyone (including you, the
+ user) from accessing them. Please see the HTML documentation for a full
+ description of this scheme.
+
+Q: Can I execute tty applications with tdesu?
+A: No. TTY application will probably never be supported. Use the Unix su for
+ those.
+ NOTE: As of version 0.94, tty _output_ _only_ is supported with the `-t'
+ switch. This disables password keeping, though.
+
+Q: What systems does KDE su support?
+A: Tested are:
+ * Linux 2.x (Redhat 6.x, Mandrake "Cooker", Debian potato, SuSE 6.1)
+ * Solaris 7 (intel)
+ * FreeBSD 3.2 (intel, w/ egcs 1.1.2)
+ It will probably work on more systems but I cannot test that.
+
+Q: Why doesn't it support every system that is out there.
+A: KDE su needs to setup a pty/tty pair for communicating with `su'. This is
+ because some `su' implementations refuse to read a password from stdin if
+ that is not a tty. Setting up a pty/tty pair is not completely portable.
+
+Q: A good debug tip?
+A: If tdesu doesn't fire up your application, use the '-t' switch.
+ This way, you'll get terminal output. Maybe there is something wrong with
+ the program you're trying to run.
+
+Q: I always get the warning: "Terminal output not available on non-terminal".
+A: Maybe you're not logged on from a terminal but probably you're using
+ UNIX98 pty's without glibc 2.1 (Linux). The glibc 2.0 ttyname() function
+ incorrectly reports that UNIX98 slave pty's are no tty's.
+
+Q: Why not use DCOP for the communications with the daemon?
+A: KDE su needs one instance of the daemon per host, instead of per desktop
+ session.

+
+ Definitions:
+
+ * "Package" refers to the collection of files distributed by the

+
+ * "Copyright Holder" is whoever is named in the copyright or

+
+ * "You" is you, if you're thinking about copying or distributing

+
+ * "Reasonable copying fee" is whatever you can justify on the

+ involved, and so on. (You will not be required to justify it to
+ the Copyright Holder, but only to the computing community at
+ large as a market that must bear the fee.)
+
+ * "Freely Available" means that no fee is charged for the item

+
+ 2. You may apply bug fixes, portability fixes and other
+ modifications derived from the Public Domain or from the Copyright
+ Holder. A Package modified in such a way shall still be considered

+ stating how and when you changed that file, and provided that you do
+ at least ONE of the following:
+
+ a) place your modifications in the Public Domain or

+ ftp.uu.net, or by allowing the Copyright Holder to include
+ your modifications in the Standard Version of the Package.
+
+ b) use the modified Package only within your corporation
+ or organization.
+
+ c) rename any non-standard executables so the names do not
+ conflict with standard executables, which must also be
+ provided, and provide a separate manual page for each
+ non-standard executable that clearly documents how it
+ differs from the Standard Version.
+
+ d) make other distribution arrangements with the Copyright
+ Holder.
+
+ 4. You may distribute the programs of this Package in object code or
+ executable form, provided that you do at least ONE of the following:
+
+ a) distribute a Standard Version of the executables and
+ library files, together with instructions (in the manual
+ page or equivalent) on where to get the Standard Version.
+
+ b) accompany the distribution with the machine-readable
+ source of the Package with your modifications.
+
+ c) accompany any non-standard executables with their
+ corresponding Standard Version executables, giving the
+ non-standard executables non-standard names, and clearly
+ documenting the differences in manual pages (or
+ equivalent), together with instructions on where to get
+ the Standard Version.
+
+ d) make other distribution arrangements with the Copyright
+ Holder.
+
+ 5. You may charge a reasonable copying fee for any distribution of
+ this Package. You may charge any fee you choose for support of this
+ Package. You may not charge a fee for this Package itself. However,
+ you may distribute this Package in aggregate with other (possibly
+ commercial) programs as part of a larger (possibly commercial)
+ software distribution provided that you do not advertise this

+ KDESU: A KDE front end for `su'.
+
+What is it?
+
+ KDE su is a graphical front end to the Unix `su' utility. It allows you
+ to run programs as another user by entering their password.
+ It is _not_ a setuid root program, it runs completely unprivileged.
+ The system's program `su' is used for acquiring privileges.
+
+Usage:
+
+ $ tdesu -h
+ $ tdesu -c konsole
+
+Please see the HTML documentation!
+
+Notes and Acknowledgements:
+
+ Credits go to Pietro Iglio. He was the original author of KDE su
+ (until version 0.3). I was writing a similar program when I
+ found out that KDE su already existed. We decided to merge our
+ projects and that I would continue with it.
+
+ If you find any bug of have a suggestion, feel free to contact me
+ at <kde@geeksrus.net>.
+
+
+License:
+
+ KDE su comes under the "Artistic License". See the file LICENSE.readme
+ for the exact terms.
