Why do I need a Prolog compiler to use Logtalk?
Currently, the Logtalk language is implemented as a Prolog extension instead of as a standalone compiler. Compilation of Logtalk source files is performed in two steps. First, the Logtalk compiler converts a source file to a Prolog file. Second, the chosen Prolog compiler is called by Logtalk to compile the intermediate Prolog file generated on the first step. The implementation of Logtalk as a Prolog extension allows users to use Logtalk together with features only available on specific Prolog compilers.
