I use it for my own numerous fixed format data file definitions, and it's been convenient and even extensible. [LeisureVolts] Description=Leisure Battery Voltage Code=AIN0 Value=0.061256 [StarterVolts] Description=Starter Battery Voltage Code=AIN1 Value=0.060943 [LeisureAmps1] Description=Leisure Battery Current Code=AIN2 Value=0.423122 I've set it up so I can understand abbreviations for the field names, for when I want to be lazy. Some of my values are dictionaries, which looks like this in my files (an alternate spelling of one of the above entries): LeisureVolts=desc:Leisure Battery Voltage code:AIN2 value:0.061256 It's simple to hook into ConfigParser to get whatever meaning you'd like, and whatever verification you'd find necessary. -- Neil Cerutti
