[erlang-questions] OTP Source File md5 checksum incorrect

[Loïc Hoguin]

You did not download a tar file, you downloaded a tar.gz and your 
browser/client automatically gunzipped it.

It's due to the HTTP headers in the response, it's sent back as an 
application/x-tar with content-encoding x-gzip, and some browsers save 
that decoded. You can use a different client to get the actual tar.gz, 
for example curl.

To avoid the issue erlang.org should not send the content-encoding 
header in the response.
