SCONSIGN(1)                       SCons 2.5.1                      SCONSIGN(1)

       sconsign - print SCons .sconsign file information

       sconsign [options...] file [...]

       The sconsign command displays the contents of one or more .sconsign
       files specified by the user.

       By default, sconsign dumps the entire contents of the specified
       file(s). Each entry is printed in the following format:

       file: signature timestamp length implicit_dependency_1: signature
       timestamp length implicit_dependency_2: signature timestamp length
       action_signature [action string]

       None is printed in place of any missing timestamp, bsig, or 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.

       By default, sconsign assumes that any file arguments that end with a
       .dbm suffix contains signature entries for more than one directory
       (that is, was specified by the SConsignFile () function). Any file
       argument that does not end in .dbm is assumed to be a traditional
       .sconsign file containing the signature entries for a single directory.
       An explicit format may be specified using the -f or --file= options.

       Various options control what information is printed and the format:

       -a, --act, --action
           Prints the build action information for all entries or the
           specified entries.

       -c, --csig
           Prints the content signature (csig) information for all entries or
           the specified entries.

       -d DIRECTORY, --dir=DIRECTORY
           When the signatures are being read from a .dbm file, or the -f dbm
           or --format=dbm options are used, prints information about only the
           signatures for entries in the specified DIRECTORY.

       -e ENTRY, --entry=ENTRY
           Prints information about only the specified ENTRY. Multiple -e
           options may be used, in which case information about each ENTRY is
           printed in the order in which the options are specified on the
           command line.

       -f FORMAT, --format=FORMAT
           The file(s) to be printed are in the specified FORMAT. Legal values
           are dbm (the DBM format used when the SConsignFile() function is
           used) or sconsign (the default format used for an individual
           .sconsign file in each directory).

       -h, --help
           Prints a help message and exits.

       -i, --implicit
           Prints the list of cached implicit dependencies for all entries or
           the the specified entries.

           Prints a pretty-printed representation of the raw Python dictionary
           that holds build information about individual entry (both the entry
           itself or its implicit dependencies). An entry's build action is
           still printed in its usual format.

       -r, --readable
           Prints timestamps in a human-readable string, enclosed in single

       -t, --timestamp
           Prints the timestamp information for all entries or the specified

       -v, --verbose
           Prints labels identifying each field being printed.

           Specifies the directory that contains the SCons Python module
           directory (e.g. /home/aroach/scons-src-0.01/src/engine). on the
           command line.
