This library is aimed at replacing the use of eqlib in QEDb. The design goals are as follows:
The reason to reimplement this part of the QEDb project from scratch is to ensure high code quality and avoid the accumulation of obscure features. When eqlib was designed many of the current design choices of QEDb were still unknown.
The library has three parts: the core functions, the interface functions, and the lemma functions. The core functions focus only on expression manipulation in general and do not implement any higher level system. The interface functions contain the expression parser, text generator (printer), and binary codec. The lemma functions implement a higher level system for building proofs (lemmas) using the algorithms implemented in this library.
Some entity names have changed with respect to eqlib in order to improve readability:

Package is pre-v1 release.
While there is nothing inherently wrong with versions of
0.*.*, it usually means that the author is still experimenting with the general direction API.
