+.Sh NAME
+.Nm pkg_delete

+.Ar pkg-name ...
+.Sh DESCRIPTION
 The
-.B pkg_delete
+.Nm
 command is used to delete packages that have been previously installed
 with the
-.B pkg_add
+.Xr pkg_add 8
 command.
 
-.SH OPTIONS
-.TP
+.Sh WARNING
+.Bf -emphasis
+Since the
+.Nm
+command may execute scripts or programs provided by a package file,
+your system may be susceptible to ``trojan horses'' or other subtle
+attacks from miscreants who create dangerous package files.
+.Pp
+You are advised to verify the competence and identity of those who
+provide installable package files.  For extra protection, examine all
+the package control files in the package record directory (
+.Pa /var/db/pkg/<pkg-name>/ ).
+Pay particular
+attention to any +INSTALL, +DEINSTALL, +REQUIRE or +MTREE_DIRS files,
+and inspect the +CONTENTS file for
+.Cm @cwd ,
+.Cm @mode 
+(check for setuid),
+.Cm @dirrm ,
+.Cm @exec ,
+and
+.Cm @unexec
+directives, and/or use the
+.Xr pkg_info 1
+command to examine the installed package control files.

 The following command line options are supported.

-.SH "TECHNICAL DETAILS"
-.B
-pkg_delete
-does pretty much what it says.  It looks for a package in /var/db/pkg
-and sets about deleting the files that make up the package and, finally,
-the record of the package itself.
-.PP
+which do not explicitly set theirs.  For most packages, the prefix will
+be set automatically to the installed location by
+.Xr pkg_add 8 .
+.Em "Optional."
+.It Fl d
+Remove empty directories created by file cleanup.  By default, only
+files/directories explicitly listed in a package's contents (either as
+normal files/directories or with the
+.Cm @dirrm
+directive) will be removed at deinstallation time.  This option tells
+.Nm
+to also remove any directories that were emptied as a result of removing
+the package.  
+.Em "Optional."
+.It Fl f
+Force removal of the package, even if a dependency is recorded or the
+deinstall or require script fails.
+.Em "Optional."
+.El
+
+.Pp
+.Sh TECHNICAL DETAILS
+.Nm
+does pretty much what it says.  It examines installed package records in 
+.Pa /var/db/pkg/<pkg-name> ,
+deletes the package contents, and finally removes the package records.
+.Pp
+If a package is required by other installed packages,
+.Nm
+will list those dependent packages and refuse to delete the package
+(unless the
+.Fl f
+option is given).
+.Pp
 If the package contains a
-.B require
+.Ar require
 file (see 
-.B pkg_create
-), then this is executed first with the flags
-.PP
-.B <script>
-.I pkg-name DEINSTALL
-.PP
-to see whether or not de-installation should continue (a non-zero exit
-status means no).
-.PP
+.Xr pkg_create 8 ),
+then this is executed first as
+.Bd -filled -offset indent -compact
+.Cm require
+.Ar <pkg-name>
+.Ar DEINSTALL
+.Ed
+(where
+.Ar pkg-name
+is the name of the package in question and
+.I DEINSTALL
+is a keyword denoting that this is a deinstallation)
+to see whether or not deinstallation should continue.  A non-zero exit
+status means no, unless the
+.Fl f
+option is specified.
+.Pp
 If a
-.B de-install
+.Cm deinstall
 script exists for the package, it is executed before any files are removed.
 It is this script's responsibility to clean up any additional messy details
 around the package's installation, since all
-.B pkg_delete
+.Nm
 knows how to do is delete the files created in the original distribution.
 The
-.B de-install
-script is called with the flags
-.PP
-.B <script>
-.I pkg-name DEINSTALL
-.PP
-Where
-.I pkg-name
-is the name of the package in question and
-.I DEINSTALL
-is a keyword denoting that this is a deinstallation.  Passing the keyword
+.Nm deinstall
+script is called as:
+.Bd -filled -offset indent -compact
+.Cm deinstall
+.Ar <pkg-name>
+.Ar DEINSTALL
+.Ed
+Passing the keyword
+.Ar DEINSTALL
 lets you potentially write only one program/script that handles all
 aspects of installation and deletion.
-.PP
+.Pp
 All scripts are called with the environment variable
-.B PKG_PREFIX
+.Ev PKG_PREFIX
 set to the installation prefix (see the
-.B -p
+.Fl p
 option above).  This allows a package author to write a script
 that reliably performs some action on the directory where the package
-is installed, even if the user might have changed it by
-.B -p
-when
-.B pkg_add
+is installed, even if the user might have changed it by specifying the
+.Fl p
+option when running
+.Nm
 or
-.B pkg_delete
-is run.
