combine multiple lines

Hi I have a file and I need to combine the lines

example:

From this

START=so_documentation Upd so_doc_source=M so_module=AGENT_LOG_ROLLOVER so_doc_\
START=type=Module


to this

START=so_documentation Upd so_doc_source=M so_module=AGENT_LOG_ROLLOVER so_doc_type=Module

Not sure the code would be since on multiple lines.

There could be multiple lines as the text wraps at 8 characters.
Its basically un-wraping the lines.

Thanks

Mike
