# Runs doxygen and stores its results in the skia-autogen repo, so that they
# can be browsed at http://skia-autogen.googlecode.com/svn/docs/html/index.html
#
# The DOXYGEN_TEMPDIR env variable is the working directory within which we will
# check out the code, generate documentation, and store the doxygen log
# (by default, /tmp/skia-doxygen). The DOXYGEN_COMMIT env variable determines
# whether docs should be commited (true by default).
#
# Sample Usage:
# export DOXYGEN_TEMPDIR=/tmp/doxygen
# export DOXYGEN_COMMIT=false
# bash update-doxygen.sh
#
# To install doxygen on most Linux systems, you can run:
# sudo apt-get install doxygen

# docs directory does not exist, skia-autogen must have been reset.
# Create a non svn docs directory instead.
mkdir docs
