# DRE 2022 - I added missed Automake inclusion because Michael Kerrisk's project because he didn't have the .am file.\
# The command option dist-bzip2 makes this into a distribution and uses bzip2 to compress the project Logger-1.0.tar.bz2 \
# tarballs for sending outside as separately self-configuring initialized projects.

# DRE 2022 -Automake initialization MUST GO HERE

# DRE 2022 - I added missed CANONCICAL HOST that describes the operting system far better than most kludged ones.

# DRE 2022 - I added missed LT_INIT which initializes autoconf and automake to create libraries - all these tools are \
# singular so you don't need them until you do.
