Detailed Description

Implementation of .tar.gz packer.

A limited subset of the .tar format is supported. This packer can open files that it wrote, but may not be able to open files from other sources, especially if they use extensions. There are restrictions on file length and character set of filenames.

We generate POSIX-compliant ustar files. As a result, the following restrictions apply to archive paths:

• Filename may not be more than 100 characters.
• Total of path + filename may not be more than 256 characters.
• For path more than 155 characters it may or may not work.
• May not contain non-ASCII characters.
