#! /usr/bin/env python
## This script demonstrates to build and install
## the documentation of a kde program with scons
##
## Thomas Nagy, 2005

## This file can be reused freely for any project (see COPYING)

## First load the environment set in the top-level SConstruct file
Import( 'env' )
myenv=env.Copy()

## The following looks complicated but it is not
## We first define a function to install all files as documentation
## The documentation is of course lying in subfolders from here
## * normal files are installed under TDEDOC/destination
## * meinproc files are not installed, but processed into a single 
##   index.cache.bz2 which is installed afterwards

## This is far more maintainable to have *one* file than
## having lots of almost empty SConscript in several folders
