To install on linux-gnu or darwin:

source <(curl -s https://raw.githubusercontent.com/dkourilov/env/master/autoinstall.sh)

To test installation:

dest=$(mktemp -d); \
cd ${dest}; \
echo Installing to ${dest}...; \
source <(curl -s https://raw.githubusercontent.com/dkourilov/env/master/autoinstall.sh);

Or to test local checkout:

mkdir /tmp/home1
dest=/tmp/home1 ./install.sh

Notes:

Mainly optimized for Iterm2/OSX.

Switching between buffers in Vim is made using <Shift>+<Control>+<Arrow> combination,
remapped to <Esc>[65;5u in Iterm2 key mappings.

Switching between tabs in tmux is done with <Control>+<Arrow>, 
remapping to <Right Alt>+<Arrow> is possible with karabiner.

Vim extensions require PowerLine-enabled font.
