#
# Usage: regpkg [options] set pkgname
#
# Registers a syspkg in the database directory,
# and optionally creates a binary package.
#
# Options:
# -q Quiet.
# -v Verbose.
# -f Force.
# -m Ignore errors from missing files.
# -u Update.
# -c Use cached information from ${BUILD_INFO_CACHE}.
# -d destdir Sets DESTDIR.
# -t binpkgdir Create a binary package (in *.tgz format) in the
# specified directory. Without this option, a binary
# package is not created.
# -M metalog Use the specified metalog file to override file
# or directory attributes when creating a binary package.
# -N etcdir Use the specified directory for passwd and group files.
#
# When -f is set: If the desired syspkg already exists, it is overwritten.
# When -u is set: If the desired syspkg already exists, it might be
# overwritten or left alone, depending on whether it's older
# or newer than the files that belong to the syspkg.
# When neither -u nor -f are set: It's an error for the desired syspkg
# to already exist.
