   3 # this script is in git as gstreamer/scripts/gst-uninstalled
   4 #
   5 # It will set up the environment to use and develop gstreamer and projects
   6 # that use gstreamer with an uninstalled git checkout of gstreamer and the
   7 # plugin modules.
   8 #
   9 # It will set up LD_LIBRARY_PATH, DYLD_LIBRARY_PATH, PKG_CONFIG_PATH,
  10 # GST_PLUGIN_PATH, GST_PLUGIN_SYSTEM_PATH, GST_REGISTRY, MANPATH, PYTHONPATH
  11 # to prefer the uninstalled versions but also contain the installed ones.
  12 # The only exception to this is, that no system installed plugins will be
  13 # used but only the uninstalled ones.
  14 #
  15 # This script assumes that the relevant modules are checked out one by one
  16 # under a given tree specified below in MYGST.
  17 #
  18 # Symlink this script in a directory in your path (for example $HOME/bin). You
  19 # must name the symlink gst-something, where something is the subdirectory
  20 # of MYGST that contains your gstreamer module checkouts.
  21 #
  22 # e.g.:
  23 # - mkdir $HOME/gst/head
  24 # - ln -sf gst-uninstalled $HOME/bin/gst-head
  25 # - checkout copies of gstreamer modules in $HOME/gst/head
  26 # - gst-head
  27
  28 # This script is run -i so that PS1 doesn't get cleared
