-.Sh NAME
-.Nm crashinfo
-.Nd "analyze a core dump of the operating system"
-.Sh SYNOPSIS
-.Nm
-.Op Fl d Ar crashdir
-.Op Fl n Ar dumpnr
-.Op Fl k Ar kernel
-.Op Ar core
-.Sh DESCRIPTION
-The
-.Nm
-utility analyzes a core dump saved by
-.Xr savecore 8 .
-It generates a text file containing the analysis in the same directory as
-the core dump.
-For a given core dump file named
-.Pa vmcore.XX
-the generated text file will be named
-.Pa core.txt.XX .
-.Pp
-By default,
-.Nm
-analyzes the most recent core dump in the core dump directory.
-A specific core dump may be specified via either the
-.Ar core
-or
-.Ar dumpnr
-arguments.
-Once
-.Nm
-has located a core dump,
-it analyzes the core dump to determine the exact version of the kernel
-that generated the core.
-It then looks for a matching kernel file under each of the subdirectories in
-.Pa /boot .
-The location of the kernel file can also be explicitly provided via the
-.Ar kernel
-argument.
-.Pp
-Once
-.Nm
-has located a core dump and kernel,
-it uses several utilities to analyze the core including
-.Xr dmesg 8 ,
-.Xr fstat 1 ,
-.Xr iostat 8 ,
-.Xr ipcs 1 ,
-.Xr kgdb 1 ,
-.Xr netstat 1 ,
-.Xr nfsstat 1 ,
-.Xr ps 1 ,
-.Xr pstat 8 ,
-and
-.Xr vmstat 8 .
-.Pp
-The options are as follows:
-.Bl -tag -width indent
-.It Fl d Ar crashdir
-Specify an alternate core dump directory.
-The default crash dump directory is
-.Pa /var/crash .
-.It Fl n Ar dumpnr
-Use the core dump saved in
-.Pa vmcore. Ns Ar dumpnr
-instead of the latest core in the core dump directory.
-.It Fl k Ar kernel
-Specify an explicit kernel file.
