Slackware package maker, version 3.14159265.

Searching for symbolic links:

No symbolic links were found, so we won't make an installation script.
You can make your own later in ./install/doinst.sh and rebuild the
package if you like.

This next step is optional - you can set the directories in your package
to some sane permissions. If any of the directories in your package have
special permissions, then DO NOT reset them here!

Would you like to reset all directory permissions to 755 (drwxr-xr-x) and
directory ownerships to root.root ([y]es, [n]o)? n

| haskell-half (half-precision floating-point)
| 
| This package supplies half-precision floating point values with
| 1 bit of sign, 5 bits of exponent, 11 bits of mantissa trailing a
| leading 1 bit with proper underflow. These arise commonly in GPU
| applications.
