# LZ4 1.9.3
# =========
# If the web site URL does not work, try www.lz4.org

# Prerequisites:
# pkg-config

# Get the source
cd
test -f installed/lz4-1.9.3.tar.gz && mv -f installed/lz4-1.9.3.tar.gz .
test ! -f lz4-1.9.3.tar.gz &&
wget https://github.com/lz4/lz4/archive/refs/tags/v1.9.3.tar.gz \
  -O lz4-1.9.3.tar.gz

# Extract the source
mkdir -p -m 0700 ~/src
cd ~/src
find -maxdepth 1 -name "lz4-*" -exec rm -r {} \;
tar xzvf ~/lz4-1.9.3.tar.gz
