databases: copyFile: does not exist

[nh2]

I got this when running hoogle-index:

Converting /tmp/textbase19836.txt
Converting textbase19836... done

hoogle-index: $HOME/.cabal/share/x86_64-linux-ghc-7.8.3/hoogle-4.2.36/databases: copyFile: does not exist (No such file or directory)

A mkdir $HOME/.cabal/share/x86_64-linux-ghc-7.8.3/hoogle-4.2.36/databases fixed it.

Maybe hoogle-index should check whether the dir exists, and create it if not?

@nh2, as of 0.3.2 hoogle-index does exactly this. Can you verify that you are running the latest version?

I still see this error with 0.3.3. Creating the directory manually addressed that error.

Incidentally, printing the version of the executable with the help information would be useful.

@acowley, the package version is now shown in the footer of the output of --help.
