Macintosh Tools for Downloading PLT Software and Documentation
The main DrScheme software archives are
distributed as MacBinaryed Stuffit files. Most
Macintosh users already have tools to unpack such a file.
It is impossible at this time for us to build user-friendly
Stuffit or Compactor files for our other
distribution archives.
Macintosh users must download ".gz" files (using binary
transfer mode, not text), and then unpack the file using the
utilities below.
WARNING: Some users have reported problems when using
Stuffit Expander to un-gzip or un-tar our
archives. If you have trouble running an executeable after unpacking
an archive with Stuffit Expander, please try using
gzip and suntar, instead.
- Stuffit Expander -
This utility unpacks .bin and .sit files. Most Macintosh users
already have this utility (or a similar application).
- gzip for Macintosh -
This is the GNU compression utility. Use the "Expand To..." menu
item to uncompress a ".gz" file. The result will be a ".tar" file...
- suntar for Macintosh -
suntar is a program for unpacking a directory structure from a
single file. Open the archive and expand it; expanding creates a new directory
in the one you choose. (Unfortunately, we can't build gzip archives
with directory structure.)
In archives with Macintosh applications (MrEd and MzScheme), if you
use the tar application instead of suntar, you will
have to perform one more step after the main archive in
unpacked: individual applications must be converted from
MacBinary. The README.MAC file in the distribution package explains
this in more detail. The suntar application does this
automatically.
Hopefully, we will be able to provide archives in a better format
in the future.
