How can I look at source code change for: PR#5312: command-line arguments @reponsefile auto-expansion feature In a web browser? I assume I would use a SVN or GIT web interface of sorts. Thanks lots! - Jakob PS. Tried to post in the thread [[Caml-list] [community poll for PR#5312] Do some OCaml Windows users still use the @responsefile feature? ] . But apparently I am not smart enough to figure out how to do so. Short story is that I relied on the @foo.rsp response semantics in 3.07pl2 and now that I am trying to upgrade to 4.00.1 I am broken. I assume I need to manually implement what we had back then. I wonder/hope that Gerd's suggestion was implemented "A cleaner solution would probably to move the responsefile implementation up to the Arg module, so that the user (a) sees it, and (b) can enable or disable it as needed."
