• Minor formatting change.

• Added basic README file.

• Added example of inserting an annotated PDF slide into the video stream.

• Removed [] indicating optional components, as the input specification syntax uses them as delimiters.

• Updated to reflect more flexible time specifications added in 9fd933f.

• Changed “segment specification” to “time specification”, and “stream specification” to “segment specification”. This makes more sense, and is consistent with the configuration parser.

• Removed the --config-help option as there appears to be no easy way to create additional standalone help-style options with argparse (it complains that there aren’t enough arguments because the positional argument is missing). The help text has been put into a separate Markdown file instead. (closes #12)
