but if you see cl::ParseCommandLineOptions in
CommandLine.cpp, it directly supports expansion over
there.<br>

Or I misunderstood something.<br>

<div>OptTable does not seem to get involved in
cl::ParseCommandLineOptions. Which one are you talking
about?</div>

<div>If you want to take a look at a real example, you may
want to look at clang/tools/driver/driver.cpp, in which
command line arguments are expanded at the most early
stage using <span
style="font-family:arial,sans-serif;font-size:13px">ExpandResponseFiles().</span></div>

I was thinking of calling cl::ExpandResponseFiles in
OptTable::ParseArgs, but I think that would be a lot of work.<br>
