Query

Where are the atom default core-packages are stored in linux.
By 'core-packages' , I mean something like,

• language-c
• language-html
• etc.

Why am I asking this,

No specific Reason, But it will help me customising atom to more extinct, which adds more meaning to ATOM: A HACKABLE TEXT EDITOR

At last,

If anything about my question or above content seems rude or mean,
SORRY FOR THAT.
