Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

# So, this is pretty horrible. If we just encode using btoa, any UTF-8 chars cause an error.
# If we use either of the workarounds on MDN[1], the £ sign is encoded wrong. I suspect
# Excel totally sucking at encodings is the reason why. So, the workaround is, to use
# the MDN workaround on chars with values > 255, and allow chars 0-255 to be encoded
# as is with btoa. Note that if you use either of the workarounds on MDN, chars
# 128-255 will be encoded as UTF-8, which includeds the £ sign. This will cause excel
# to choke on these chars. Excel will still choke on chars > 255, but at least the £
# sign works now...
