Parts is a group of tools designed to work with the partitioning scheme used by IBM's PC-DOS. Existing popular tools available for Linux/UNIX include fdisk, sfdisk, cfdisk & parted and if you're feeling adventurous there's always dd and od.
The gap I think I can fill with my tools involves two areas. First and most important to people that are building multiboot systems, I have built up a rule set that a disks partitioning must meet for it to be handled by an array of different operating systems (Most notably Linux & Windows). Secondly I have opened up the partitioning for all to see so there are no myths or simply misunderstandings. Please note the group of tools are only in command line form, so if you are not familiar with issuing commands by the command line these tools are not for you, at least not in their current form.
As a result of beginning the development of Parts I have quickly found there is little detail on the internet that covers the structure of a primary extended partition. Admittedly the primary partition table, hence the layout of the fields in a partition record are all detailed, however when a disaster hits a little more information would be nice (as I'd know from personal experience). I have therefore considered it time to then produce at least some detail in non code form to detail the structure of the contents of primary extended partitions.
Well, be my guest and take a look around. And if you have the time, give me feed back on the tools or information provided.
