 201 mk-basefile, create minimal base files for a Linux distritubtion
 202
 203    Copyright (C) 2011-2016 by Thomas Lange
 204
 205 Usage: mk-basefile [OPTION] ... DISTRIBUTION
 206
 207    -s                   Show list of supported linux distributions
 208    -a                   Add xtattrs, acl and selinux properties to the tar file.
 209    -d DIR               Use DIR for creating the temporary subtree structure.
 210    -z                   Use gzip for compressing the tar file.
 211    -J                   Use xz for compressing the tar file.
 212    -k                   Keep the temporary subtree structure, do not remove it.
 213    -h                   Print help.
 214
 215  Usage example: mk-basefile -J STRETCH64
 216  This will create a STRETCH64.tar.xz basefile.
