    doc: add script to compute texi files dependencies · 628ceac6
    Stefano Sabatini authored
    Replace the inline awk script with a Perl script which tracks the
    dependencies recursively.
    
    This allows to correctly track dependencies for files including files
    with a second level include (for example: ffmpeg-devices.texi ->
    devices.texi -> outdevs.texi).
    
    This also adds a dependency on perl for computing the dependencies, which
    should not be a problem since perl is already required all the way for
    building documentation.
