I would like to slightly modify the output of the standard doclet. I don't want however to write my own new doclet, because my changes are not really big.
I have looked for tutorials, but found only those for creating new doclets. There is no answer here either:
How to tweak the standard doclet--not write an entirely-new doclet?
How to extend JavaDoc 5.0 standard doclet?
How can I achieve modified output?
I have found source files that I can modify here:
https://jdk7.java.net/source.html
standard doclet is in openjdk/langtools/src/share/classes/com/sun/tools/doclets
