# this script is in git as gstreamer/scripts/gst-uninstalled

#

# 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 LD_LIBRARY_PATH, DYLD_LIBRARY_PATH, PKG_CONFIG_PATH,

# GST_PLUGIN_PATH, GST_PLUGIN_SYSTEM_PATH, GST_REGISTRY, MANPATH, PYTHONPATH

# 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 MYGST.

#

# 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 MYGST 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

# This script is run -i so that PS1 doesn't get cleared
