TODO
-----

(-) Add filter_flags, disable_as_needed, disable_no_undefined functions
(-) inarytools.dobin() needs a destinationFile parameter to rename the binary
(-) inarytools.dodoc() may need an optional mode parameter for chmodding installed
    documents
(-) inarytools.dodoc() does not allow passing a directory as source
(-) rename() could be dropped in favor of move()
(-) inarytools.dosed() does not provide all sed functionality. It only supports
    substitution. Rename the function or add support for other sed commands.
(-) It is not clear which function takes source file paths relative to workDir or
    relative to installDir (dosed, insinto -> workDir, rename -> installDir).
    We may consider using different module names to distinguish these like
    sourceutils, installutils, etc.
