Explanation of XMakefile Syntax/Tokens |||MW_XMK_<...>|||

Hi,

im trying to adapt the file "R2013b\toolbox\idelink\foundation\xmakefile\registry\templates\defgmake.mkt" for the IAR compiler and need to change some parts of this template makefile. But I cannot find any documentation about syntax and tokens for this. I would like to know how to use the |MW_XMK_<tokens>||| tokens used within these files (see following picture).

Greetings, Daniel
