gitignore for netbeans project that ignores generic configuration files that are generated by netbeans

sample gitignore for netbeans projects

#ant specific
dist/
build/

#netbeans specific
core
nbproject/*
!nbproject/project.properties
!nbproject/project.xml

#java specific
*.class

#general swap/backup files
*.so
*.log
*.out
*~
*.swp
*.DS_Store
*.lock

Question: Why do you do the following?

!nbproject/project.properties
!nbproject/project.xml

These files are showing up in my repository, but they shouldn't be necessary should they? Yet if I removed them from tracking, Netbeans won't recognize the project even though they are still there. I guess Netbeans only sees what git sees? Very confused n00b here.

! means not, so those files will show up. That is necessary so that all files in nbproject are ignored except project.properties and project.xml

That is not necessary , Netbeans automaticamente ignora las carpetas privadas.
