     was built

SYNOPSIS

     gnunet-config [-b BACKEND | --supported-backend=BACKEND] [-C | --cflags]
                   [-c FILENAME | --config=FILENAME] [-F | --full] [-f | --filename]
                   [-h | --help] [-j | --libs] [-L LOGLEVEL | --loglevel=LOGLEVEL]
                   [-o OPTION | --option=OPTION] [-p | --prefix] [-r | --rewrite]
                   [-S -|-list-sections] [-s SECTION | --section=SECTION]
                   [-V VALUE | --value VALUE] [-v | --version]

DESCRIPTION

     gnunet-config can be used to read or modify GNUnet configuration files.  It can also provide
     information to properly build applications on top of GNUnet, like appropriate values for
     CFLAGS or the installation prefix.

     -b BACKEND | --supported-backend=BACKEND
             Tests whether the specified BACKEND is supported by the current installation.  The
             backend must match the name of a plugin, e.g. "namestore_postgres" for the Postgres
             database backend of the "NAMESTORE" service. If the BACKEND is supported, gnunet-
             config will return a status code of 0 (success), otherwise 77 (unsupported).  When
             this option is specified, no other options may be specified. Specifying this option
             together with other options will cause gnunet-config to return a status code of 1
             (error).

     -C | --cflags
             Print an appropriate value for CFLAGS to compile applications on top of GNUnet.

     -c FILENAME | --config=FILENAME
             Use the configuration file FILENAME.

     -F | --full
             Write the full configuration, not just the deltas to the defaults.

     -f | --filename
             Try to perform expansions as if the option values represent filenames (will also be
             applied even if the option is not really a filename).

     -h | --help
             Print short help on options.

     -j | --libs
             Print an appropriate value for LIBS to compile applications on top of GNUnet.

     -L LOGLEVEL | --loglevel=LOGLEVEL
             Use LOGLEVEL for logging.  Valid values are DEBUG, INFO, WARNING and ERROR.

     -o OPTION | --option=OPTION
             Which configuration option should be accessed or edited.  Required to set a value.
             If not given, all values of a given section will be printed in the format "OPTION =
             VALUE".

     -p | --prefix
             Print GNUnet's installation prefix (for example /usr/local.)

     -r | --rewrite
             Write the configuration to file, even if it did not change.

     -S -|-list-sections
             List available configuration sections for use with --section.

     -s SECTION | --section=SECTION
             Which configuration section should be accessed or edited.  Required option.

     -V VALUE | --value VALUE
             Configuration value to store in the given section under the given option.  Must only
             be given together with -s and -o options.

     -v | --version
             Print GNUnet version number.

     The full documentation for gnunet is maintained as a Texinfo manual.  If the info(1) and
     gnunet programs are properly installed at your site, the command

           info gnunet

     should give you access to the complete handbook,

           info gnunet-c-tutorial

     will give you access to a tutorial for developers.

     Depending on your installation, this information is also available in gnunet(7) and
     gnunet-c-tutorial(7).
