.SH "NAME"
sconsign \- print SCons signature file information
.SH "SYNOPSIS"
.HP \w'\fBsconsign\fR\ 'u
\fBsconsign\fR [\fIoptions\fR...] [\fIfile\fR...]
.SH "DESCRIPTION"
.PP
The
\fBsconsign\fR
command displays the contents of one or more signature ("\fBsconsign\fR") files specified by the user\&.
.PP
By default,
\fBsconsign\fR
dumps the entire contents of the specified file(s)\&. Without the verbose option, each entry is printed in the following format:
.sp
.if n \{\
.RS 4
.\}
.nf
file: signature timestamp length
        implicit_dependency_1: signature timestamp length
        implicit_dependency_2: signature timestamp length
        \&.\&.\&.
        action_signature [action string]
.fi
.if n \{\
.RE
.\}
.PP
\fBNone\fR
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\&.
.PP
By default,
\fBsconsign\fR
assumes that any
\fIfile\fR
arguments that end with a
\fB\&.dbm\fR
suffix contains signature entries for more than one directory (that is, was specified by the
\fBSConsignFile\fR
function)\&. Any
\fIfile\fR
argument that ends in
\fB\&.dblite\fR
is assumed to be a traditional
\fB\&.sconsign\fR
file containing the signature entries for a single directory\&. If neither of those is true,
\fBsconsign\fR
attempts to guess the format\&. If that does not work, an explicit format may be specified using the
\fB\-f\fR
or
\fB\-\-format=\fR
options\&.
.PP
If there are no
\fIfile\fR
arguments, the name
\&.sconsign\&.dblite
is assumed\&.
.SH "OPTIONS"
.PP
Various options control what information is printed and the format:
.PP
\-a, \-\-act, \-\-action
.RS 4
Prints the build action information for all entries or the specified entries\&.
.RE
.PP
\-c, \-\-csig
.RS 4
Prints the content signature (csig) information for all entries or the specified entries\&.
.RE
.PP
\-d DIRECTORY, \-\-dir=DIRECTORY
.RS 4
When the signatures are being read from a
\fB\&.dbm\fR
file, or the
\fB\-f dbm\fR
or
\fB\-\-format=dbm\fR
options are used, prints information about only the signatures for entries in the specified
\fIDIRECTORY\fR\&.
.RE
.PP
\-e ENTRY, \-\-entry=ENTRY
.RS 4
Prints information about only the specified
\fIENTRY\fR\&. Multiple \-e options may be used, in which case information about each
\fIENTRY\fR
is printed in the order in which the options are specified on the command line\&.
.RE
.PP
\-f FORMAT, \-\-format=FORMAT
.RS 4
The file(s) to be printed are in the specified
\fIFORMAT\fR\&. Legal values are
\fBdbm\fR
(the DBM format used when the
\fBSConsignFile\fR
function is used) or
\fBsconsign\fR
(the default format used for an individual
\fB\&.sconsign\fR
file in each directory)\&.
.RE
.PP
\-h, \-\-help
.RS 4
Prints a help message and exits\&.
.RE
.PP
\-i, \-\-implicit
.RS 4
Prints the list of cached implicit dependencies for all entries or for the specified entries\&.
.RE
.PP
\-\-raw
.RS 4
Prints a pretty\-printed representation of the raw Python dictionary that holds build information about individual entries (both the entry itself and its implicit dependencies)\&. An entry\*(Aqs build action is still printed in its usual format\&.
.RE
.PP
\-r, \-\-readable
.RS 4
Prints timestamps in a human\-readable string, enclosed in single quotes\&.
.RE
.PP
\-t, \-\-timestamp
.RS 4
Prints the timestamp information for all entries or the specified entries\&.
.RE
.PP
\-v, \-\-verbose
.RS 4
Prints labels identifying each field being printed\&.
.RE
.SH "ENVIRONMENT"
.PP
SCONS_LIB_DIR
.RS 4
Specifies the directory that contains the SCons Python module directory (e\&.g\&.
/home/aroach/scons\-src\-0\&.01/src/engine)\&. on the command line\&.
