+description:
+  Short alias for installing cabal package from git source repository.
+  .
+  @$> cabalg git://github.com/biegunka/biegunka.git --branch=develop@
+  .
+  is just a shorthand for
+  .
+  @$> create-dir /temp/directory
+  $> git clone --branch develop --single-branch --depth=1 --quiet git://github.com/biegunka/biegunka.git /temp/directory
+  $> change-dir /temp/directory
+  $> cabal install@
+  $> change-dir-back
+  $> remove-dir /temp/directory@
+  .
+  If current directory has '.cabal-sandbox', 'cabalg' will attach the given repo to it.
+  Also notice, that '--single-branch' flag  comes with 'git-1.7.10' (<https://lkml.org/lkml/2012/3/28/418>) only, so you should have it.
+  .
+  It seems to be that 'cabalg' is windows-compatible too.
