olex is an easy to use LL(1) parser generator in C++, generating C++ code. The latest version is olex.alfa-pl13.tar.gz (154k). Check the CHANGELOG to check what's new.
To know more about olex, read the online manual. The source LaTeX file is in the package. Despite what the manual says my new email address is bvh-cplusplus@irule.be for questions and suggestions on olex.
