    1.20 -    $myname - populate the target root file system
    1.21 -
    1.22 -SYNOPSIS
    1.23 -    $myname OPTIONS -s source_root -d destination_root
    1.24 -
    1.25 -DESCRIPTION
    1.26 -    $myname will 'populate' your target root file system ('src_dir') with
    1.27 -    libraries from the toolchain (eg. libc.so...), storing the result into
    1.28 -    'dst_dir'.
    1.29 -
    1.30 -OPTIONS
    1.31 -    -s src_dir
    1.32 -        use 'src_dir' as the un-populated (source) root directory
    1.33 -
    1.34 -    -d dst_dir
    1.35 -        use 'dst_dir' as the place to put the populated root directory
    1.36 -
    1.37 -    -l name1[:name2[...]]
    1.38 -        Always add the specified shared library/ies name1, name2... from the
    1.39 -        toolchain (in the sys-root). Actual library names are searched as
    1.40 -        follows (where 'name' is replaced with the given name) in the
    1.41 -        sys-root directory:
    1.42 -          - libname.so
    1.43 -          - name.so
    1.44 -          - name
    1.45 -        If the file is found, then the SONAME of the library is used, and the
    1.46 -        library is copied with that name. If the library was not found, this
    1.47 -        yields an error (unless -f was given).
    1.48 -
    1.49 -    -L file
    1.50 -        Read 'file' for a list of shared libraries to always add from the
    1.51 -        toolchain. The file should contain one library name per line; text
    1.52 -        after a # is ignored until the end of the line; spaces are ignored;
    1.53 -        empty lines are ignored. Libraries are searched for as with -l.
    1.54 -
    1.55 -    -f  force execution: if destination directory already exists, it will be
    1.56 -        removed first; if a specified library (above) was not found, continue.
    1.57 -
