Usage: rpmdev-newspec [option]... [appname[.spec]]

Options:
  -o FILE, --output FILE
                 Output the specfile to FILE. "-" means stdout. The default is
                 derived from <appname>, or "$DEFSPEC" if <appname> is
                 not given.
  -t TYPE, --type TYPE
                 Force use of the TYPE spec template. The default is guessed
                 from <appname>, falling back to "$DEFTYPE" if the guesswork
                 does not result in a more specific one or if <appname> is not
                 given.${types:+ Available types:
$types}
  -m, --macros   Emit templates using macros instead of shell style variables.
                 Configuration variable: NEWSPEC_PREFER_MACROS, default is off.
  -r VERSION, --rpm-version VERSION
                 Filter out some spec file constructs not needed by the
                 specified rpm(build) version and newer ones. Configuration
                 variable: NEWSPEC_MIN_RPMVER, default is system rpm version.
  -h, --help     Show this usage message and exit.
  -v, --version  Print version information and exit.

Files:
$SPECDIR
  Directory for specfile templates.
$CONFIG
  System wide configuration.
