Hi all again. I've also added to file text.py code to manage the warning messages reported by the amsmath package. They look like:
Package amsmath Warning: Foreign command \over;
(amsmath)                \frac or \genfrac should be used instead
(amsmath)                 on input line 56.
    The code is:
texmessage.packagewarning = texmessagepattern(re.compile(r"^package\s+(?P<packagename>\S+)\s+warning\s*:[^\n]+(?:\n\(?(?P=packagename)\)?[^\n]*)*", re.MULTILINE | re.IGNORECASE), "ignoring generic package warning")
which I've added after the definition of texmessage.rerunwarning. Of course the definitions of both defaulttexmessagesend and defaulttexmessagesdefaultrun must be modified to also include the new texmessage.packagewarning RE.
    Hope this helps, best regards.
