# HOW TO EDIT THIS FILE:
# The "handy ruler" below makes it easier to edit a package description.  Line
# up the first '|' above the ':' following the base package name, and the '|'
# on the right side marks the last column you can put a character in.  You must
# make exactly 11 lines for the formatting to be correct.  It's also
# customary to leave one space after the ':' except on otherwise blank lines.

brotli: brotli (Brotli compression format)
brotli:
brotli: Brotli is a general purpose lossless compression algorithm that
brotli: compresses data using a combination of a modern variant of the LZ77
brotli: algorithm, Huffman coding, and second order context modeling, with a
brotli: compression ratio comparable to the best currently available general
brotli: purpose compression methods. It is similar in speed with deflate but
brotli: offers more dense compression.
