But that's bad practice, detrimental in particular to CASs which don't
enjoy much funding, in general.
Every time a grant application to support such a CAS is made, it's a
struggle to justify it, not the least due to lack of citations.
In this case (symbolics computations like this), it's 'ginac' alone, I believe.
