Token             # of times encountered in training

pgood and pbad represent the raw likelihood that a message containing
this token is a nonspam or spam respectively

fw is Robinson's weighted index, which combines pgood and pbad to give
a value that will be close to zero if a message containing this token
is likely to be a nonspam and close to one if it's likely to be a spam

the next two columns are ln (fw) and ln (1-fw) respectively; these are
useful in an R table (see the -R option).

The last column contains a + if this token contributes to the final
"spamicity" value, and a - if it was excluded because it's closer than
min_dev to 0.5.

Hope that helps..........
