## Description
A simple tar & compress library that nicely wraps external system calls.

## Installation
`gem install archive-tar-external`
   
## Synopsis
```ruby
require 'archive/tar/external' # or 'archive-tar-external'
   
# Create an archive of all files with an ".rb" extension, the long way.
t = Archive::Tar::External.new('test.tar')
t.create_archive('*.rb')
t.compress_archive('gzip')
   
# Same, but the short way.
t = Archive::Tar::External.new('test.tar', '*.rb', 'gzip')
```

## Prerequisites
* The 'tar' command line program.
* At least one compression program, e.g. gzip, bzip2, zip, etc.
   
## Known Issues

### Solaris
The tar program that comes with Solaris will not raise an error if you
try to expand a file from an archive that does not contain that file.

### OSX
It appears that the BSD tar that ships on Mac does not implement the -u
option properly by default, and will add a file to the archive even if
the timestamp of the file hasn't changed.

The OSX issue was effectively addressed in version 1.5.0, where the default
archive format was added and set to 'pax'.
