Free structure software for linux

e2fsimage allows you to create ext2 filesystem images, mostly used on Linux systems, by copying an entire directory structure into an ext2 formatted image without needing root permissions.
Without this tool you need to loopback-mount an existing filesystem image and copy all files there as root.
This application is usually used by people creating rescue disks, initrds, bootable floppys or CDs or the more. Especially on build hosts where they do not have root permissions and the ptrace() bug is already fixed.
Enhancements:
- support for user ids in .UIDGID file and usernames resolved by passwd file
- free uiddb structure after use
- manpage updated

Xephyrus Data Structures Tag Library provides an easy way to create and manipulate the contents of common Java data-structures such as maps and lists.
Enhancements:
- The library was polished up.
- Several improvements were made and a few bugs were fixed.
- This version is aimed at Java 5 and JSP 2.0.

atropine is a screen-scraping library built on top of BeautifulSoup.
atropine helps programmers make assertions about document structure while getting at the data they are interested in.
atropine library was developed under Python.
Special thanks to Piet Delport for the resolver, null resolver, chain-of-resolvers ideas.
Please note, using this library is not as complicated as it sounds, it consists of only 275 lines of python.
It is better to get no data than to get the wrong data.
The key to screen-scraping the right data is to make a painful amount of assertions about document structure
Enhancements:
- Some unused imports were removed.
- A text only version of the reference was added.
- Things were generally tidied up.

Linux Video Maker is useful for DVD/(S)VCD structure generating, ready for record on CD/DVD. Its in fact graphics interface (GUI) for transcode, mplex, DVDAuthor and few other programs...

Using of these programs for this purpose is uncomfortable and sometimes difficult especially for beginners because it involves a lot of knowledge about DVD/(S)VCD technology and video converting.

Linux Video Maker binds funcionality of 8 exterior programs and prevents from making many mistakes mainly in conversion process which can take a lot of time as AVI files uses complicated video algorithms (DIVX).

Program doesnt contain yet too many advanced options but it allow generate a standard DVD/(S)VCD structure without any problems.

Program in 2 GUI languages: english and polish !

Aapl is a C++ template library for generic programming.
Aapl supports different generic programming paradigms by providing variations of standard data structures. For example, a by-value linked list template may be used to store a user supplied type such as an integer.
A different list template allows the user to define the data structure that is to be used as the element. A third list template allows a single instance of a data structure to be an element in multiple lists.
Wherever possible, Aapl data structures do not depend on heap memory allocation. There are variations of the linked list and AVL tree that allow the programmer to allocate a collection of elements statically and insert/remove them at will.
Aapl data structures do not have their data members hidden behind a strict abstraction layer. Aapl makes very little use of the private keyword. Though data abstractions can be a useful programming technique to quickly produce very robust code, they can inhibit functionality when the data structure is the centre of much attention. Therefore Aapl leaves the use of abstractions up to the programmer.
Enhancements:
- A transfer function has been added to the double lists and AVL trees.
- Remaining double list and AVL tree copy constructors and assignment operators have been changed to implement a deep copy, rather than a shallow copy.
- All copy constructors and assignment operators now implement a deep copy.
- Deep and shallow copy functions have been removed.

M3U-Playlist Manager is an administration of loose m3u-playlists in tree structure. Simple mouse-click to add or remove a song from playlist with currently running Song in the Player.

And other interesting functions. Supporting only XMMS at the moment.

HTML Objects is a Perl module library for turning HTML tags into Perl objects. HTML Objects allows Web pages to be manipulated as a data structure rather than text.

Once manipulation is done, the entire page is generated via depth-first recursion.
