I find it very useful to spend 5 minutes a day to keep a small log of what was worked on, major bugs or reviews and a general small status report. It makes rolling up into a bigger status report easier when required, or handy as a reference before you go into meetings etc.
rstdiary will take a flat RST based input file and chunk it into some reasonable looking static-HTML that looks something like this. It's split by month with some minimal navigation. Copy the output directory somewhere and it is done.
It might also serve as a small example of parsing and converting RST nodes where it does the chunking; unfortunately the official documentation on that is "to be completed" and I couldn't find anything like a canonical example, so I gathered what I could from looking at the source of the transformation stuff. As the license says, the software is provided "as is" without warranty!
So if you've been thinking "I should keep a short daily journal in a flat-file and publish it to a web-server but I can't find any software to do just that" you now have one less excuse.
