--INFORMATIONS------------------------------------------------------------------
If you find ErrorHandler useful or even if you are not satisifed, then mail me!
I'm likely to improve this package, so it is recommended to visit the download
page to always get the newest version. I undertake to notify everyone, I'd
contacted with, about every new release. You can also subscribe to ErrorHandler
mailing list: errorhandler-subscribe@yahoogroups.com (few trtaffic)
About Documentation
I warmly appreciate if you could contribute to the documentaion with description
or example of usage, how-to's. Please note that the documentation is written in
DocBook format. If you are unfamiliar with it, you can write a plain text file,
too, I'll convert it.
All features tested on:
+ Debian (2.2) Apache 1.3.9 PHP 4.2.1 (client-side: NS 4.77, Opera 5.12)
+ SuSE (7.3+) Apache 1.3.24 PHP 4.2.0 (client-side: Opera 6.0B2)
ErrorHandler works with 4.0.6. If you use older version of PHP, you must upgrade.
Konqueror (2.2.1) can not display the content of CONSOLE window, it is a known
issue, but I could not figure out why. Any suggestions?
