Curl - Command line equivalent C++ code

  Ever needed the source code corresponding to a curl command line? Fortunately, the developers were nice to add an option to generate the C++ source code.

   curl command has an option --libcurl FILE to generate the source code for any http request. This basically saves the code in the specified file and executes the actual http request. The most often used curl request is to get repo to download Android's source code.

         curl https://storage.googleapis.com/git-repo-downloads/repo

This along with --libcurl generates this nice helper function,

curl https://storage.googleapis.com/git-repo-downloads/repo --libcurl curl.cpp

/********* Sample code generated by the curl command line tool **********

  curl_easy_setopt(hnd, CURLOPT_NOPROGRESS, 1L);

  curl_easy_setopt(hnd, CURLOPT_USERAGENT, "curl/7.37.1");
