+.SH NAME
+truncate - truncate files to zero length
+.SH SYNOPSIS
+.B truncate
+[
+.I find-options
+] 
+.SH DESCRIPTION
+Truncate uses find with the specified options to find regular files.
+Each file is truncated to zero length, but owner, permissions, and
+last-modified date are preserved. If the user doesn't have write
+permissions for a file, a message is printed and the file is skipped.
+.SH DIAGNOSTICS
+Various error messages from the used commands.
+.SH AUTHOR
+Peter J. Holzer (hjp@wsr.ac.at)
