/**

The `args` property allows to explicitly set arguments for the execution. The
name of the executable will always be the first element in the arg-vector.

\section args_details Details

\subsection args_operations Operations

\subsubsection args_set_var Setting values

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.
