Adjusted comment to recent changes. git-svn-id: svn://svn.cc65.org/cc65/trunk@5727 b7a2c559-68d2-44c3-8de9-860c34a00d81

# Default configuration built into ld65 (allowing for 3KB in LC)
Reworked and improved the SYMBOLS section. The old syntax (using symbol = value) is now gone, attributes are used instead. The SYMBOLS section does now support imports, so the linker config can be used to force symbols (and therefore module) imports. Evaluation of start address and size for memory areas has been delayed even further, so it is now possible to use the values from one memory area in the definition of the next one. git-svn-id: svn://svn.cc65.org/cc65/trunk@4851 b7a2c559-68d2-44c3-8de9-860c34a00d81

Use the new linker features in apple2.cfg. This makes apple2-tgi.cfg obsolete. git-svn-id: svn://svn.cc65.org/cc65/trunk@3648 b7a2c559-68d2-44c3-8de9-860c34a00d81

SYMBOLS {
Moved Apple EXEHDR to separate module (similiar to CBMs). git-svn-id: svn://svn.cc65.org/cc65/trunk@5708 b7a2c559-68d2-44c3-8de9-860c34a00d81

The Apple2 linker configs basically cover two dimension of settings: 1. BIN vs. SYS vs. Loader 2. With Quit code vs. w/o Quit code vs. full LC Up two now these two dimensions were sort of folded into a number of useful combinations. However with the new asm config and the upcominger overlay config we end up with just to many configs. Therefore now the second dimension isn't expressed anymore as distinct config. Rather the user has to override __LCADDR__ and __LCSIZE__ in order use the Quite code area or the full LC. git-svn-id: svn://svn.cc65.org/cc65/trunk@5722 b7a2c559-68d2-44c3-8de9-860c34a00d81

Avoid mixing of memory areas and segments in address computations (and made move of segment INIT somewhat more readable). git-svn-id: svn://svn.cc65.org/cc65/trunk@5726 b7a2c559-68d2-44c3-8de9-860c34a00d81
