karmakAra and karmakara

[Chandrasekaran, Periannan]

The classical Tamil text cilappatikAram (2nd-4th century AD)
uses the word
"karumakArar" ("karmakAra") in the sense of some craftsman such as
as a smith (blacksmith) in chapter 5's beginning where the
auhtor iLaGkO gives a long list of occupations engaged in
by the residents of maruvUrppAkkam a "blue collar"-like or
"downtown"-like area of pUmpukAr the Tamil port city.
I do not have the text with me right now.
Hope somebody else could help here with the specific line.

Regards
Chandra
