CRM114 How are you finding it ?

[Randal, Phil]

Using CentOS 5 x64, I installed according to the wiki as it was.

I had to make the crm114/*.crm files executable for it to work, so I
added that step to the wiki.

The only changes I made in crm114.cf were:

  crm114_learn 1
  crm114_autolearn 1
  crm114_dynscore_factor -0.2

Cheers,

Phil
