-  // Run a process or a builtin, interpreting the command line as
-  // whitespace-separated, potentially quoted program path/builtin name,
-  // arguments, and redirects. Throw std::invalid_argument on the parsing
-  // error, ios::failure on the underlying OS error, process_error on the
-  // process running error and std::system_error on the builtin running error.
-  //
-  // To run a system utility rather than a builtin prefix its name with `^`,
-  // for example:
-  //
-  // ^cat --squeeze-blank file
-  //
-  // The process environment path is unused and must point to the empty
-  // process path.
-  //
-  // Currently only the following stdout redirects are supported:
-  //
-  // >file   # Overwrite file.
-  // >>file  # Append to file.
-  //
-  // In particular, the file descriptor cannot be specified. The file path can
-  // optionally be separated from '>' by whitespaces. Note that redirects are
-  // distinguished from arguments by the presence of leading '>' and prior to
-  // possible substitutions (so the redirect character cannot be the result of
-  // a substitution; see below).
-  //
-  // The relative redirect file paths are completed using the command
-  // current working directory. Note that if it is altered via the process
-  // environment, then the new value is used.
-  //
-  // The command line elements (program, arguments, etc) may optionally
-  // contain substitutions - variable names enclosed with the substitution
-  // symbol ('@' by default) - which are replaced with the corresponding
-  // variable values to produce the actual command. Variable names must not
-  // contain whitespaces and an attempt to substitute an unknown or a
-  // malformed variable is an error. Double substitution character ('@@' by
-  // default) is an escape sequence.
-  //
-  // If the variable map is absent, then '@' has no special meaning and is
-  // treated as a regular character.
-  //
-  // The callback function, if specified, is called prior to running the
-  // command process with the substituted command elements and including
-  // redirects which will be in the "canonical" form (single argument without
-  // space after '>'). The callback can be used, for example, for tracing the
-  // resulting command line, etc.
