This package level exported mutable string contains the location of the executable. Normally, you do not need to worry about this, as CohomCalg is distributed with Macaulay2, and this variable points to the executable which comes with Macaulay2.
This can be useful to find the executable, or, if you have compiled a newer version, then you can set this to be where you keep that.
