# Temporary build locations:
export TMPBUILD=$TMP/build-$PKGNAM
export PKG=$TMP/package-$PKGNAM

# Determine the CFLAGS for the known architectures:

# If you really need these (let's say you're doing virus scanning
# and this *would* speed things up quite a bit) you can create
# the pre-parsed files yourself using file's -C option.

# Apply generic Slackware packaging policies:
cd $PKG
slackgzpages -i # compress man & info pages and delete usr/info/dir

# Perform any final checks on the package:
