my question is regarding the way a bibtex-style field is defined in a bst file. I would like to have the following example below explained piece by piece, to understand what each piece is doing. I would like to be in a position to make changes to that example myself.

FUNCTION {format.eprint}
{ eprint duplicate$ empty$
    'skip$
    { "\eprint"
      archive empty$
        'skip$
        { "[" * archive * "]" * }
      if$
      "{" * swap$ * "}" *
    }
  if$
}
