     1.8 +NAME
     1.9 +    $myname - populate the target root file system
    1.10  
    1.11 -    -s dir
    1.12 -        use 'dir' as the un-populated (source) root directory
    1.13 +SYNOPSIS
    1.14 +    $myname OPTIONS -s source_root -d destination_root
    1.15  
    1.16 -    -d dir
    1.17 -        use 'dir' as the place to put the populated root directory
    1.18 +DESCRIPTION
    1.19 +    $myname will 'populate' your target root file system ('src_dir') with
    1.20 +    libraries from the toolchain (eg. libc.so...), storing the result into
    1.21 +    'dst_dir'.
    1.22  
    1.23 -    -f  force execution: if destination directory already exists,
    1.24 -        it will be removed first.
    1.25 +OPTIONS
    1.26 +    -s src_dir
    1.27 +        use 'src_dir' as the un-populated (source) root directory
    1.28 +
    1.29 +    -d dst_dir
    1.30 +        use 'dst_dir' as the place to put the populated root directory
    1.31 +
    1.32 +    -l name1[:name2[...]]
    1.33 +        Always add the specified shared library/ies name1, name2... from the
    1.34 +        toolchain (in the sys-root). Actual library names are searched as
    1.35 +        follows (where 'name' is replaced with the given name) in the
    1.36 +        sys-root directory:
    1.37 +          - libname.so
    1.38 +          - name.so
    1.39 +          - name
    1.40 +        If the file is found, then the SONAME of the library is used, and the
    1.41 +        library is copied with that name. If the library was not found, this
    1.42 +        yields an error (unless -f was given).
    1.43 +
    1.44 +    -L file
    1.45 +        Read 'file' for a list of shared libraries to always add from the
    1.46 +        toolchain. The file should contain one library name per line; text
    1.47 +        after a # is ignored until the end of the line; spaces are ignored;
    1.48 +        empty lines are ignored. Libraries are searched for as with -l.
    1.49 +
    1.50 +    -f  force execution: if destination directory already exists, it will be
    1.51 +        removed first; if a specified library (above) was not found, continue.
