# this snippet is to be included by both our docbook manuals
# and gtk-doc API references

# it adds an upload target to each of these dir's Makefiles

# each Makefile.am should define the following variables:
# - DOC: the base name of the documentation
#        (faq, manual, pwg, gstreamer, gstreamer-libs)
# - FORMATS: the formats in which DOC is output
#            (html ps pdf)

# if you want to use it, make sure your $HOME/.ssh/config file contains the
# correct User entry for the Host entry for the DOC_SERVER

# This is an include file specifically tuned for building documentation
# for GStreamer plug-ins
