1. build container image (first time only)
```
docker build -t lx2160a_build docker
# optional with an apt proxy, e.g. apt-cacher-ng
# docker build --build-arg APTPROXY=http://127.0.0.1:3142 -t lx2160a_build docker
```
2. invoke build script in working directory
```
docker run -i -t -v "$PWD":/work lx2160a_build $(id -u) $(id -g)
docker run -i -t -v "$PWD":/work lx2160a_build -u $(id -u) -g $(id -g)
```
### rootless Podman
Due to the way podman performs user-id mapping, the root user inside the container (uid=0, gid=0) will be mapped to the user running podman (e.g. 1000:100).
Therefore in order for the build directory to be owned by current user, `-u 0 -g 0` have to be passed to *docker run*.
## Build with host tools
Simply running ./runme.sh will check for required tools, clone and build images and place results in images/ directory.

# shFlags is an advanced command-line flag library for Unix shell scripts.
#
# Author: kate.ward@forestent.com (Kate Ward)
# https://github.com/kward/shflags
#
# This module implements something like the gflags library available
# from https://github.com/gflags/gflags.
#
# FLAG TYPES: This is a list of the DEFINE_*'s that you can do. All flags take
# a name, default value, help-string, and optional 'short' name (one-letter
# name). Some flags have other arguments, which are described with the flag.
#
# DEFINE_string: takes any input, and interprets it as a string.
#
# DEFINE_boolean: does not take any arguments. Say --myflag to set
# FLAGS_myflag to true, or --nomyflag to set FLAGS_myflag to false. For short
# flags, passing the flag on the command-line negates the default value, i.e.
# if the default is true, passing the flag sets the value to false.
#
# DEFINE_float: takes an input and interprets it as a floating point number. As
# shell does not support floats per-se, the input is merely validated as
# being a valid floating point value.
#
# DEFINE_integer: takes an input and interprets it as an integer.
#
# SPECIAL FLAGS: There are a few flags that have special meaning:
# --help (or -?) prints a list of all the flags in a human-readable fashion
# --flagfile=foo read flags from foo. (not implemented yet)
# -- as in getopt(), terminates flag-processing
#
# EXAMPLE USAGE:
#
# -- begin hello.sh --
# #! /bin/sh
# . ./shflags
# DEFINE_string name 'world' "somebody's name" n
# FLAGS "$@" || exit $?
# eval set -- "${FLAGS_ARGV}"
# echo "Hello, ${FLAGS_name}."
# -- end hello.sh --
#
# $ ./hello.sh -n Kate
# Hello, Kate.
#
# CUSTOMIZABLE BEHAVIOR:
#
# A script can override the default 'getopt' command by providing the path to
# an alternate implementation by defining the FLAGS_GETOPT_CMD variable.
#
# NOTES:
#
# * Not all systems include a getopt version that supports long flags. On these
# systems, only short flags are recognized.
#==============================================================================
# shFlags
#
# Shared attributes:
# flags_error: last error message
# flags_output: last function output (rarely valid)
# flags_return: last return value
#
# __flags_longNames: list of long names for all flags
# __flags_shortNames: list of short names for all flags
# __flags_boolNames: list of boolean flag names
#
# __flags_opts: options parsed by getopt
#
# Per-flag attributes:
# FLAGS_<flag_name>: contains value of flag named 'flag_name'
# __flags_<flag_name>_default: the default flag value
# __flags_<flag_name>_help: the flag help string
# __flags_<flag_name>_short: the flag short name
# __flags_<flag_name>_type: the flag type
#
# Notes:
# - lists of strings are space separated, and a null value is the '~' char.

# A basic boolean flag. Boolean flags do not take any arguments, and their
# value is either 1 (false) or 0 (true). For long flags, the false value is
# specified on the command line by prepending the word 'no'. With short flags,
# the presence of the flag toggles the current value between true and false.
# Specifying a short boolean flag twice on the command results in returning the
# value back to the default value.
#
# A default value is required for boolean flags.
#
# For example, lets say a Boolean flag was created whose long name was 'update'
# and whose short name was 'x', and the default value was 'false'. This flag
# could be explicitly set to 'true' with '--update' or by '-x', and it could be
