+.Sh NAME
+.Nm procmap
+.Nd print a procfs map file
+.Sh SYNOPSIS
+.Nm procmap
+.Ar <pid>
+.Nm procmap
+curproc
+.Sh DESCRIPTION
+The
+.Nm
+utility prints the full contents of a procfs map file.
+Using a program such as cat is unreliable for this purpose, since the kernel
+must be able to write the entire contents at once, which requires a sufficiently
+large buffer.
