Hello,

I've made some tweaks to the bootstrap.sh here:

1. It avoids downloading the additional haskell package tarballs if

these tarballs are already present in the current

directory. Motivation: easily install on machines not connected to the

internet, and make install more robust against local internet

connection problems (we have a lot of these).

2. The SCOPE_OF_INSTALLATION variable use is slightly changed to allow

installing cabal-install executable without either using or altering

the user's package database, or replacing any cabal-install executable

which they already have.

Example:

ghc-pkg init /home/jake/test_cabal/

SCOPE_OF_INSTALLATION='--global --package-db=/home/jake/test_cabal/packagedb' PREFIX=/home/jake/test_cabal/prefix ./bootstrap.sh

Is it possible to put these changes into the main cabal repo?  If

there are some changes which would make the patch acceptable then

please let me know. Also, is there a simpler way to meet these goals

which I missed?

Thanks,

Jake Wheat
