#  This script uses the indentation of the first input line as indentation
#  for the entire output. This is usefull for indenting code blocks in an
#  editor such as vi: simply indent the first line and then pass the block
#  thru this script, e.g. using the ex '!' statement.
#
#  E.g. add following line to your ~/.vimrc file for indenting
#  a selected piece of C-code (via <V>) using <F12>:
#  map <F12> :!indt<CR>
