+Help: Read config from a file

+Example: --config file.txt $URL

+Specify a text file to read curl arguments from. The command line arguments
+found in the text file will be used as if they were provided on the command
+line.
+
+Options and their parameters must be specified on the same line in the file,
+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 contains whitespace (or starts with : or =), 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.se/docs/"
+
+ # --- 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 ---
+
+When curl is invoked, it (unless --disable is used) checks for a default
+config file and uses it if found, even when --config is used. The default
+config file is checked for in the following places in this order:
+
+1) "$CURL_HOME/.curlrc"
+
+2) "$XDG_CONFIG_HOME/.curlrc" (Added in 7.73.0)
+
+3) "$HOME/.curlrc"
+
+4) Windows: "%USERPROFILE%\\.curlrc"
+
+5) Windows: "%APPDATA%\\.curlrc"
+
+6) Windows: "%USERPROFILE%\\Application Data\\.curlrc"
+
+7) Non-Windows: use getpwuid to find the home directory
+
+8) On Windows, if it finds no .curlrc file in the sequence described above, it
+checks for one in the same dir the curl executable is placed.
+
+On Windows two filenames are checked per location: .curlrc and _curlrc,
+preferring the former. Older versions on Windows checked for _curlrc only.
+
+This option can be used multiple times to load multiple config files.
