Custom revision properties in Mercurial?

Question

Can I setup a custom property for my hg repository so that I could store/retrieve its value for each revision? Like, weather in Tokyo at the time of commit, etc.

This could be a job for:

• a pre-commit hook in Mercurial (not a precommit hook which runs before the internal commit occurs, when the list of files to commit is already known. But "pre-commit", a generic hook which runs before the commit begin)
• a git pre-commit hook (but you need to add your file with the updated weather information to the list of files to be committed)

In both cases, said hooks would get the information you need and update one specific file in charge of keeping that property.
