       spectool - manual page for spectool v1.0.10rpmdev1

SYNOPSIS

       spectool [<options>] <specfile>

DESCRIPTION

       Spectool is a tool to expand and download sources and patches from specfiles.

       If you experience problems with specific specfiles, try to run

	      rpmbuild --nobuild --nodeps <specfile>

       on  the	file which might give a clue why spectool fails on a file (ignore anything about missing sources or patches). The plan is to catch
       errors like this in spectool itself and warn the user about it in the future.

OPTIONS

   Operating mode:
       -l, --lf, --list-files
	      lists the expanded sources/patches (default)

       -g, --gf, --get-files
	      gets the sources/patches that are listed with a URL

       -h, --help
	      display this help screen

   Files on which to operate:
       -A, --all
	      all files, sources and patches (default)

       -S, --sources
	      all sources

       -P, --patches
	      all patches

       -s, --source x[,y[,...]]
	      specified sources

       -p, --patch a[,b[,...]]
	      specified patches

   Miscellaneous:
       -d, --define 'macro value'
	      defines RPM macro 'macro' to be 'value'

       -C, --directory dir
	      download into specified directory (default '.')

       -R, --sourcedir
	      download into rpm's %{_sourcedir}

       -n, --dryrun, --dry-run
	      don't download anything, just show what would be done

       -f, --force
	      try to unlink and download if target files exist

       -D, --debug
	      output debug info, don't clean up when done

FILES

       /etc/rpmdevtools/curlrc
