@hackage recursive-line-count0.1

This program can be used to count lines of code in a program and display them hierarchically. For example, to tally up lines of Haskell code in a git repository:

git ls-files '*.hs' | recursive-line-count

More precisely, recursive-line-count takes a list of file names on standard input, counts lines in each file, and displays the results in a GtkTreeView.
