               Building an imapsync docker image from Debian
=======================================================================

Nearly verbatim copy from https://imapsync.lamiral.info/INSTALL.d/Dockerfile 
(verbatim but the Dockerfile rcs tag $ removed because it would conflict)

## Dockerfile for building a docker imapsync image

# Id: Dockerfile,v 1.42 2022/04/04 19:16:50 gilles Exp gilles $
# I use the following command to build the image:
#
#  docker build -t gilleslamiral/imapsync . 
#
# where this Dockerfile is in the current directory
# 
# This Dockerfile build an image with two imapsync
# 1) One comes from https://imapsync.lamiral.info/imapsync
#    and goes to /usr/bin/imapsync in the Docker image
#    It is used with the command:
#
#    docker run gilleslamiral/imapsync imapsync ...
# 
# 2) One comes from the local file ./imapsync
#    and goes to /imapsync in the Docker image
#    It is used with the command:
#
#    docker run gilleslamiral/imapsync /imapsync ...

# I thank you very much
# I like thanks
# I like stars
# I like money to keep on doing this stuff
