+Long: config
+Arg: <file>
+Help: Read config from a file
+Short: K
+---
+Specify which config file to read curl arguments from. The config file is a
+text file in which command line arguments can be written which then will be
+used as if they were written on the actual command line.
+
+Options and their parameters must be specified on the same config file line,
+separated by whitespace, colon, or the equals sign. Long option names can
+optionally be given in the config file without the initial double dashes and
+if so, the colon or equals characters can be used as separators. If the option
+is specified with one or two dashes, there can be no colon or equals character
+between the option and its parameter.
+
+If the parameter is to contain whitespace, the parameter must be enclosed
+within quotes. Within double quotes, the following escape sequences are
+available: \\\\, \\", \\t, \\n, \\r and \\v. A backslash preceding any other
+letter is ignored. If the first column of a config line is a '#' character,
+the rest of the line will be treated as a comment. Only write one option per
+physical line in the config file.
+
+Specify the filename to --config as '-' to make curl read the file from stdin.
+
+Note that to be able to specify a URL in the config file, you need to specify
+it using the --url option, and not by simply writing the URL on its own
+line. So, it could look similar to this:
+
+url = "https://curl.haxx.se/docs/"
+
+When curl is invoked, it always (unless --disable is used) checks for a
+default config file and uses it if found. The default config file is checked
+for in the following places in this order:
+
+1) curl tries to find the "home dir": It first checks for the CURL_HOME and
+then the HOME environment variables. Failing that, it uses getpwuid() on
+Unix-like systems (which returns the home dir given the current user in your
+system). On Windows, it then checks for the APPDATA variable, or as a last
+resort the '%USERPROFILE%\\Application Data'.
+
+2) On windows, if there is no _curlrc file in the home dir, it checks for one
+in the same dir the curl executable is placed. On Unix-like systems, it will
+simply try to load .curlrc from the determined home dir.
+

+# --- Example file ---
+# this is a comment
+url = "example.com"
+output = "curlhere.html"
+user-agent = "superagent/1.0"
+
+# and fetch another URL too
+url = "example.com/docs/manpage.html"
+-O
+referer = "http://nowhereatall.example.com/"
+# --- End of example file ---
+.fi
+
+This option can be used multiple times to load multiple config files.
