NAME

       sconsign - print SCons signature file information

SYNOPSIS

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

DESCRIPTION

       The sconsign command displays the contents of one or more signature database (sconsign)
       files used by the scons build tool.

       By default, sconsign dumps the entire contents of the sconsign file(s). Without the
       verbose option, 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, 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.

       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 ends in .dblite is assumed to be a traditional sconsign
       file containing the signature entries for a single directory. If neither of those is true,
       sconsign attempts to guess the format. If that does not work, an explicit format may be
       specified using the -f or --format= options.

       If there are no file arguments, the name .sconsign.dblite is assumed.

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 for the specified
           entries.

       --raw
           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's build action is still printed in its usual format.

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

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

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

ENVIRONMENT

       SCONS_LIB_DIR
           Specifies the directory that contains the SCons Python module directory (e.g.
           /home/aroach/scons-src/SCons).
