A question came up on the GnuCash mailing list asking how difficult it would be to convert stocks listed on foreign exchanges into local currency when the stock-prices are updated. I thought it was an excellent question and an issue well worth addressing.
After a bit of hacking, I managed to clobber out a very rough (but working) currency converter for Finance::Quote. It's going to be changed to make it nicer, but I managed to write a trivial application which can convert between two currencies on the command-line.
Did lots of tidy-up work on Finance::Quote. Added testing scripts and fixed the documentation and made a few code optimisations. I'll probably release a new version shortly, with currency-conversion support due for the version after that.
The joy of coding has kept me up past midnight. I must be getting to sleep.
