This is a Bash currency converter that processes the currency
rates file generated by the units_cur Python script distributed
with GNU Units.

Usage:
currencyconv.sh convert [amount][in currency] [out currency]

Currencies are specified with ISO standard 3-letter codes (eg.
USD, EUR).

In addition, the same script can generate a currency rates text
file and the gophermaps and directories for my "Gopher Banker"
Gopher currency converter. Conversion from Gopher "search"
queries using GNU Units (more efficient) uses the gopherconvert.sh
script.

I'll write a README at some point which will explain the details.
Actually if you're interested, ask me, then I might actually get
around to writing it.
