Compression

You know that Rebol compress function compress data, but you can manipulate also TAR.GZ archives and ZIP archives.
For TAR.GZ archives there are the following script:

• http://www.rebol.org/download-a-script.r?script-name=gunzip.r
• http://www.rebol.org/download-a-script.r?script-name=gzip.r
• http://www.rebol.org/download-a-script.r?script-name=gunzip.r
• 
  

They can be used this way:
do %tar.r
do %gzip.r
write/binary %test.tgz gzip tar [%some-files ...]


Resulting archive is usually smaller than a *.zip of the same files
To decompress use  gunzip.r script

For ZIP archives there is the following script: http://www.rebol.org/download-a-script.r?script-name=rebzip.r
usage: zip/deep %new-zip.zip [ %readme.txt "An example" ftp://192.168.1.10/my-file.txt %my-directory/ ]
to unzip unzip %new-zip.zip

If you want to only explore a zip file without decompress it, you can use this script: http://www.rebol.org/download-a-script.r?script-name=zip.r
