+
+To set a the argument vector the following syntax can be used.
+
+\code{.cpp}
+args = value;
+args(value);
+\endcode
+
+`std::initializer_list` is among the allowed types, so the following syntax is also possible.
+
+\code{.cpp}
+args = {value1, value2};
+args({value1, value2});
+\endcode
+
+Below the possible types for `value` are listed, with `char_type` being either `char` or `wchar_t`.
+
+\paragraph args_set_var_value value
+
+ - `std::basic_string<char_type>`
+ - `const char_type * `
+ - `std::initializer_list<const char_type *>`
+ - `std::vector<std::basic_string<char_type>>`
+
+Additionally any range of `std::basic_string<char_type>` can be passed.
+
+\subsubsection args_append_var Appending values
+
+To append a the argument vector the following syntax can be used.
+
+\code{.cpp}
+args += value;
+\endcode
+
+`std::initializer_list` is among the allowed types, so the following syntax is also possible.
+
+\code{.cpp}
+args += {value1, value2};
+\endcode
+
+Below the possible types for `value` are listed, with `char_type` being either `char` or `wchar_t`.
+
+\paragraph args_append_var_value value
+
+ - `std::basic_string<char_type>`
+ - `const char_type * `
+ - `std::initializer_list<const char_type *>`
+ - `std::vector<std::basic_string<char_type>>`
+
+Additionally any range of `std::basic_string<char_type>` can be passed.
+
+
+\subsection args_example Example
+
+The overload form is used when more than one string is passed, from the second one forward.
+I.e. the following expressions have the same results:
+
+\code{.cpp}
+spawn("gcc", "--version");
+spawn("gcc", args ="--version");
+spawn("gcc", args+="--version");
+spawn("gcc", args ={"--version"});
+spawn("gcc", args+={"--version"});
+\endcode
+
+\note A string will be parsed and set in quotes if it has none and contains spaces.
