`time' is a program that measures many of the CPU resources, such as time and memory, that other programs use. The GNU version can format the output in arbitrary ways by using a printf-style format string to include various resource measurements. Some systems do not provide much information about program resource use; `time' reports unavailable information as zero values. See the file INSTALL for compilation and installation instructions. Mail suggestions and bug reports for GNU time to firstname.lastname@example.org. Please include the version of `time', which you can get by running `time --version', and the operating system and C compiler you used.
