 % The |script| and |scriptscript| options reverse this decision by forcing interatom spacing to more closely resemble that of |\textstyle|. Table~2 lists the amount of space that \textsf{innerscript} inserts between various pairs of math classes for each option, and adjustments of this type will resemble the changes to the summation from equation~(2). The |inner| package option forces all spacing around |\mathinner| subformulas to take the value it would if the formula had type |\mathord|. Traditionally \TeX\ places more space around |\mathinner| subformulas than it does around |\mathord| atoms, so loading \textsf{innerscript} with |inner| will remove a certain amount of space from math formulas. Changes of this type will typically resemble the adjustment to the function $g$ from equation~(2). Users who want to further change the spacing in their math formulas should manually add glue, muglue, or |\kern| to their math lists or provide new values for the |\Umath| spacing parameters in their document preamble.
