 These are written in standard Python without any external libraries. I
 have only tested these on Linux, but there should be no OS limitations.
 
+Currently, these tools comprise automatic work handlers so that
+certain third-party software (that do the actual computation) can
+access Primenet (mersenne.org):

 mfloop.py
 ---------
 
-Automatic work assignment and submission script for mfakto and
-possibly other similar applications.
-
-Mfakto does trial division of Mersenne numbers with OpenCL, so it can
-speed up this stage greatly with GPUs. It relies on manual work
-assignment and submission from/to http://www.mersenne.org/. mfloop.py
-automates this, so mfakto can keep working indefinitely.
-
-This script is intended to run in parallel with mfakto. It uses
-lockfiles to avoid conflicts when accessing files. A typical command
-line would be
-
-mfloop.py -u teknohog -p salasana -n 10 -t 7200 -e 70
-
-This would attempt updates every 2 hours, aiming to keep 10
-assignments in worktodo.txt. The upper limit of exponent range is
-increased to 70 (if lower than that). Also,
-
-* Use -t 0 for a single update without looping.
-
-* Use -n 0 to finish work and not get any new assignments.
+For trial factoring with mfakto (should work with mfaktc too)
 
-Optionally, it can also use gpu72.com for work assignments. The
-results are still submitted to mersenne.org, so you need login
-credentials for both sites, for example:
 
-mfloop.py -u teknohog -p merspass -U teknohog -P gpupass
+lliki.py
+--------
 
-In this case, there is a hardcoded minimum of 72 for the upper limit
-of the exponent range. If a fetch from gpu72.com fails, it will try
-primenet instead.
-
-Run mfloop.py -h for more details on options.
-
-Some of the ideas are adapted from http://www.gpu72.com/spider/.

-* Other work types besides trial factoring. This should be trivial to
-  implement, at least with similar worktodo.txt/results.txt formats...
-
-* .. but the only other major application seems to be CUDALucas, which
-  accepts work as a commandline option. A Python wrapper for this
-  should be relatively simple, as the network part is already done. I
-  do not have Nvidia cards, though, but I am seriously considering to
-  get one for this, despite my firm opensource stance :-j
