This is a draft version, and I'm looking for feedback, like ways the
specs could be improved, mistakes to fix, better ways to do things.
Also feel free to ask any questions. I plan to freeze the specs
after 3 weeks (or so), and update glBSP to generate the new formats.
Summary of the changes:
- V5 GL-Nodes, which removes all the limits. V3 removed the segs
and vertex limits, but V5 also prevents overflowing the number
of nodes/subsectors. The other versions (V1, V3, V4) are now
deprecated, only V2 and V5 need to be supported.
- support for storing information in the GL level marker lump
(GL_MAP01 etc). The format is a text file with KEYWORD=VALUE
pairs. Currently there are keywords for a timestamp, a level
checksum, and the name of the node-builder.
- support for level names longer than 5 letters. When this happens,
the GL level marker becomes "GL_LEVEL", and the name of the normal
level is stored inside this lump using the "LEVEL" keyword.
- a standard way of creating Extension lumps.
Cheers

If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
Version 5 of the GL-Nodes specification has been updated. Draft #2 makes the following changes:
1. The GL_SSECT structure has been changed to prevent possible problems with mis-alignment. The 'count' field is now 4-bytes long, as in V3. It was noted that some processors (Alpha, and SH-4 used in the Dreamcast) cannot handle mis-aligned longs, and some processors (x86-64) incur a large speed penalty.
2. The date and time format has been changed slightly to be compatible with the ISO standard. The '-' character is now used as the separator in the date (instead of '/'), and the fraction of a second is respresented with '.' followed by four digits (instead of ':' followed by two digits).
>> Example: 2005-04-30 15:49:40.1234
This is still a draft, and further suggestions and/or corrections are welcome. The full specifications can be found here:
