[Serusers] functions to add/replace body/headers

Hi, are there functions in ser (or one of its modules) that can be used within another module to add or replace headers or message bodies? I am thinking of something like: add_header(&msg, header) replace_header(&msg, oldheader, newheader) and add_body(&msg, body) replace_body(&msg, oldbody, newbody) If not, then is the best way to achieve this the use of the textops functions from modules/text? thanks, Stephan -- Stephan Reiff-Marganiec Research Fellow Department of Computing Science; University of Stirling email: srm(a)cs.stir.ac.uk tel: 01786 46 7448 -- The University of Stirling is a university established in Scotland by charter at Stirling, FK9 4LA.
