<refsect1 id='description'><title>DESCRIPTION</title>
<para>The
<command>sconsign</command>
command
displays the contents of one or more signature
("<markup>sconsign</markup>")
files specified by the user.</para>

<para>By default,
<command>sconsign</command>
dumps the entire contents of the
specified file(s).
Without the verbose option,
each entry is printed in the following format:</para>

<literallayout class="monospaced">
file: signature timestamp length
        implicit_dependency_1: signature timestamp length
        implicit_dependency_2: signature timestamp length
        ...
        action_signature [action string]
</literallayout>

<para><emphasis role="bold">None</emphasis>
is printed
in place of any missing timestamp, build signature ("bsig"),
or content signature ("csig")
values for
any entry
or any of its dependencies.
If the entry has no implicit dependencies,
or no build action,
the lines are simply omitted.
The verbose option expands the display into a more human
readable format.
</para>

<para>By default,
<command>sconsign</command>
assumes that any
<emphasis>file</emphasis>
arguments that end with a
<markup>.dbm</markup>
suffix contains
signature entries for
more than one directory
(that is,
was specified by the
<emphasis role="bold">SConsignFile</emphasis>
function).
Any
<emphasis>file</emphasis>
argument that ends in
<markup>.dblite</markup>
is assumed to be a traditional
<markup>.sconsign</markup>
file containing the signature entries
for a single directory.
If neither of those is true,
<command>sconsign</command>
attempts to guess the format.
If that does not work,
an explicit format
may be specified using the
<option>-f</option>
or
<option>--format=</option>
options.
</para>
<para>
If there are no
<emphasis>file</emphasis>
arguments, the name
<filename>.sconsign.dblite</filename>
is assumed.
</para>

<refsect1 id='options'><title>OPTIONS</title>
<para>Various options control what information is printed
and the format:</para>

<variablelist>

  <listitem>
<para>Prints the content signature (csig) information
for all entries or the specified entries.</para>

<para>When the signatures are being
read from a
<markup>.dbm</markup>
file, or the
<option>-f dbm</option>

<option>--format=dbm</option>
options are used,
prints information about
only the signatures

  </varlistentry>
  <varlistentry>
  <term>-e ENTRY, --entry=ENTRY</term>
  <listitem>
<para>Prints information about only the specified

  <listitem>
<para>The file(s) to be printed

Legal values are
<emphasis role="bold">dbm</emphasis>
(the DBM format used
when the
<emphasis role="bold">SConsignFile</emphasis>
function is used)
or
<command>sconsign</command>
