| 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). | |
