-# It will set up the environment to use and develop gstreamer and projects
-# that use gstreamer with an uninstalled git checkout of gstreamer and the
-# plugin modules.
+# It will set up the environment to use and develop pitivi with an
+# uninstalled git checkout of pitivi and GES.
 #
 # It will set up LD_LIBRARY_PATH, DYLD_LIBRARY_PATH, PKG_CONFIG_PATH,
 # to prefer the uninstalled versions but also contain the installed ones.
-# The only exception to this is, that no system installed plugins will be
-# used but only the uninstalled ones.
 #
-# This script assumes that the relevant modules are checked out one by one
-# under a given tree specified below in MYPITIVI.
-#
-# Symlink this script in a directory in your path (for example $HOME/bin). You
-# must name the symlink gst-something, where something is the subdirectory
-# of MYPITIVI that contains your gstreamer module checkouts.
-#
-# e.g.:
-# - mkdir $HOME/gst/head
-# - ln -sf gst-uninstalled $HOME/bin/gst-head
-# - checkout copies of gstreamer modules in $HOME/gst/head
-# - gst-head
+# When you run the script for the first time, the script will checkout
+# everything you need to get started. If you want to do it yourself, set
+# MYPITIVI accordinly
 
-# This script is run -i so that PS1 doesn't get cleared
-
-# Change this variable to the location of your gstreamer git checkouts
+# Change this variable to the location of you choice, that either:
+#  + contains pitivi, ges and gst-python checkouts that you have already
+#    compiled.
+#
+#  + an empty location where you have R+W access, so the script sets up
+#    everything for you.  (better choice in the case you are starting
+#    with PiTiVi devel)
