Remark: I think chdir() is not a good option here because if one module does chdir to include other modules which also do chdir(), then chdir() is required before every individual "load". Otherwise the current directory is basically unknown to any particular script. -- Peter Michaux | Remark: I think chdir() is not a good option here because if one module does chdir to include other modules which also do chdir(), then chdir() is required before every individual "load".
