     2 # contained in the HPACK spec. It's pretty simple to run:

     3 #   python make_outgoing_tables.py < http2_huffman_table.txt > Http2HuffmanOutgoing.h

     4 # where huff_outgoing.txt is copy/pasted text from the latest version of the

     5 # HPACK spec, with all non-relevant lines removed (the most recent version

     6 # of huff_outgoing.txt also lives in this directory as an example).
