std::size_t	Myra::number_of_processing_units (void)
	Get the number of processing units available. This returns the sum of CPUs, cores, hyperthreads, etc. More...
VStr	Myra::run_command_and_get_vector (const std::string &cmd)
	Run a command and get all of the output from STDOUT. More...
std::string	Myra::run_command_and_get_string (const std::string &cmd)
	Run a command and get all of the output from STDOUT. More...
std::string	Myra::read_text_file (const std::string &filename)
	Read an entire text file. More...
void	Myra::write_file (const std::string &filename, const std::string &text)
	Write a text file. This writes the file to a temporary location, then renames it to the requested name. More...
bool	Myra::is_root (void)

	Build a text string that tells us approximately when a specific event took place. More...
std::string	Myra::approximate_time (const TP &when)
	Similar to the other approximate_time() function, but takes a TP reference. More...
std::string	Myra::cpp_demangle (const std::string &str)
	Demangle the given C++ name. This is compiler-specific. More...
FD	Myra::create_pid_lockfile (const std::string &name)
