Re: How to let procmail use mre memory?

Hello,

There are several programs already available that you can call from
procmail for this:
        w3m       ->    http://w3m.sourceforge.net/
        w3mmee    ->    http://pub.ks-and-ks.ne.jp/prog/w3mmee/
        links     ->    http://links.sourceforge.net/
        elinks    ->    http://elinks.or.cz/about.html
        html2text ->    http://man-wiki.net/index.php/1:html2text
        lynx      ->    http://man-wiki.net/index.php/1:lynx


I am alredy using html2text, but if you fetch the HTML page you have  it
in memory and then I have to pipe it through 3 different filters because
the pages are not always in the same format.

If I use your recipe the pages are unreadable...

First I have to use a SED script to cut from the beging to a marker  and
then from a second marker to the end and add new <html>...</html> tags.

And now I can use html2text to get the stuf I like.

The problem ist here:

At home I can use temporary files, but not on my Mail-Backup.
