+.TH memeat 1 "2021-10-08"
+.SH NAME
+memeat \- allocates memory until killed
+.SH SYNOPSIS
+.SY memeat
+.RI [ maximum ]
+.YS
+.SH DESCRIPTION
+This program will allocate all available memory mebibyte by mebibyte over some time. If optional
+.I maximum
+is provided, then program will terminate after reaching this amount of allocated memory in mebibytes. In case this
+value is invalid or does not make sense, then program will not attempt to consume the memory, and will indicate a
+failure in the exit status.
+.SH EXIT STATUS
+Program is expected to be terminated externally, so exit status may depend on the execution environment. If
+.I maximum
+is specified, then 0 will be returned after reaching the boundary, or 1 will be returned if the provided argument
+could not be understood.
+.SH SEE ALSO
+.BR free (3)
