std::string	Ase::anklang_runpath (RPath rpath, const String &segment)
	Retrieve various resource paths at runtime.
const char *()	Ase::_ (const char *string)
	Translate message strings in the Anklang/ASE text domain.
std::string()	Ase::_ (const std::string &string)
	Translate message strings in the Anklang/ASE text domain.
const char *()	Ase::_ (const char *string, const char *plural, int64_t n)

	Override the environment variable $ASE_COLOR (which may contain "always", "never" or "auto").
bool	Ase::AnsiColors::colorize_tty (int fd)
	Check whether the tty fd should use colorization, checks ASE_COLOR if fd == -1.
std::string	Ase::AnsiColors::color (Colors acolor, Colors c1, Colors c2, Colors c3, Colors c4, Colors c5, Colors c6)
	Return ANSI code for the specified color if stdout & stderr should be colorized, see colorize_tty().

	Return ANSI code for the specified color.
std::string	Ase::cpu_arch ()
	Retrieve string identifying the CPU architecture.
String	Ase::cpu_info ()
	The returned string contains: number of online CPUs, a string describing the CPU architecture, the vendor and finally a number of flag words describing CPU features plus a trailing space.
