This is the Clp project. For information on the purpose of
this project please visit https://github.com/coin-or/Clp

The information below should be migrated into README.md or the User's Guide.

Running clp gives you some hints.  It can do a unit test (clp -unitTest) and solve netlib 
problems (-netlib or -netlibp using primal).  It can also solve problems and set tolerances etc.  Just do 

clp 
 
and then try ? or setting various stuff.

clp filename   reads file, does presolve and dual algorithm
clp filename -primalsimplex would use primal instead

On Linux clp can do file completion and line editing if it can find history, readline and termcap..  

If you want to stress the code you can set various stuff e.g. dantzig pricing
 and then go into netlib testing.  I do not guarantee that it will solve all 
netlib if you get too creative.  For instance using presolve makes netlib 
solve faster - but pilot87 prefers a large infeasibility weight.  So

clp -presolve on -dualbound 1.0e10 -netlib

works well.

There are samples in ./Samples.  To create an executable - testit do

make DRIVER=minimum to use minimum.cpp

or whichever driver you want.  A list is in Makefile.

Three useful samples are:

minimum.cpp  This is the simplest possible program to read an mps file.

defaults.cpp.  This does not do much more, but it does it in much more 
complicated way by specifically setting defaults so it does give more
useful information.  It also prints a solution in a format "similar" to that
of MPSX.

presolve.cpp.  This is a good driver for larger problems.

Other ones can get complicated so start simple and work your way up.
