Things left to do

As Unifpack was written several tasks were deferred for future versions, otherwise we will never have a version ever released, this is a list of the most important ones, some of them are under development, but others are still on a design stage, please don't take the order too seriously.

• Improve group labeling, symmetric search should accept a word on which symmetry in preserved, this means that the whole labeling mechanism requires a change, since they must accept parameters, otherwise an internal variable must be kept.
• Improve device drivers, including colors, line styles, fill styles and pick correlation.
• Polygon types should define an special point (center) this would make pick correlation simpler.
• GUI's should be reconsidered but only if uniflang power is not lost.
• Subgroup calculation.
• Find side pairings.
• Tilings.
• Find -presentations from any presentation, using Riemann-Hurwitz theorem.
• More tests and a shell script that runs the tests and inform the results. A torture test for uniflang is specially interesting.
• Integrate the language and the kernel.
• Improve the caclulator, specially error recovery, device control, garbage collector, add user defined functions, and better control structures (as do's and for's). A ``compiler'' may be interesting too.
• Words should keep a pointer to the SymbolTable.
• Numberics had to be check and improved, some problems seems to be appearing.
• Provide man(1) pages.
