+.TH DSCVERIFY 1 "Debian Utilities" "DEBIAN" \" -*- nroff -*-
+.SH NAME
+dscverify \- verify the validity of a Debian package
+.SH SYNOPSIS
+\fBdscverify\fR [\fB\-\-keyring \fIkeyring\fR] ... \fIchanges_or_buildinfo_or_dsc_filename\fR ...
+.SH DESCRIPTION
+\fBdscverify\fR checks that the GPG signatures on the given
+\fI.changes\fR, \fI.buildinfo\fP or \fI.dsc\fR files are good signatures
+made by keys in the current Debian keyrings, found in the \fIdebian-keyring\fR
+package.  (Additional keyrings can be specified using the
+\fB--keyring\fR option any number of times.)  It then checks that the
+other files listed in the \fI.changes\fR, \fI.buildinfo\fP or \fI.dsc\fR
+files have the
+correct sizes and checksums (MD5 plus SHA1 and SHA256 if the latter are
+present).  The exit status is 0 if there are no problems and non-zero
+otherwise.
+.SH OPTIONS
+.TP
+.BI \-\-keyring " " \fIkeyring\fR
+Add \fIkeyring\fR to the list of keyrings to be used.
+.TP
+\fB\-\-no-default-keyrings\fR
+Do not use the default set of keyrings.
+.TP
+\fB\-\-no-conf\fR, \fB\-\-noconf\fR
+Do not read any configuration files.  This can only be used as the
+first option given on the command-line.
+.TP
+\fB\-\-nosigcheck\fR, \fB\-\-no\-sig\-check\fR, \fB-u\fR
+Skip the signature verification step. That is, only verify the sizes and
+checksums of the files listed in the \fI.changes\fR, \fI.buildinfo\fP or
+\fI.dsc\fR files.
+.TP
+\fB\-\-verbose\fR
+Do not suppress GPG output.
+.TP
+.TP
+.BR \-\-help ", " \-h
+Display a help message and exit successfully.
+.TP
+.B \-\-version
+Display version and copyright information and exit successfully.
+.SH "CONFIGURATION VARIABLES"
+The two configuration files \fI/etc/devscripts.conf\fR and
+\fI~/.devscripts\fR are sourced by a shell in that order to set
+configuration variables.  Environment variable settings are ignored
+for this purpose.  If the first command line option given is
+\fB\-\-noconf\fR or \fB\-\-no-conf\fR, then these files will not be
+read.  The currently recognised variable is:
+.TP
+.B DSCVERIFY_KEYRINGS
+This is a colon-separated list of extra keyrings to use in addition to
+any specified on the command line.
+.SH KEYRING
+Please note that the keyring provided by the debian-keyring package
+can be slightly out of date. The latest version can be obtained with
+rsync, as documented in the README that comes with debian-keyring.
+If you sync the keyring to a non-standard location (see below),
+you can use the possibilities to specify extra keyrings, by either
+using the above mentioned configuration option or the \-\-keyring option.
+
+Below is an example for an alias:
+
+alias dscverify='dscverify \-\-keyring ~/.gnupg/pubring.gpg'
+.SH STANDARD KEYRING LOCATIONS
+By default dscverify searches for the debian-keyring in the following
+locations:
+
+- ~/.gnupg/trustedkeys.gpg
+
+- /srv/keyring.debian.org/keyrings/debian-keyring.gpg
+
+- /usr/share/keyrings/debian-keyring.gpg
+
+- /usr/share/keyrings/debian-maintainers.gpg
+.SH "SEE ALSO"
+.BR gpg (1),
+.BR gpg2 (1),
+.BR devscripts.conf (5)
