/** The cmd property allows to explicitly set commands for the execution.

The overload form applies when only one string is passed to a launching function.
The string will be internally parsed and split at spaces.

The following expressions are valid, with `value` being either a C-String or
a `std::basic_string` with `char` or `wchar_t`.

\code{.cpp}
cmd="value";
cmd(value);
\endcode

The property can only be used for assignments.
