"$glue = MuGlue($spec);"

"$glue = MuGlue($spec,$plus,$pfill,$minus,$mfill);"

Creates a MuGlue object (similar to Glue). $spec can be a string in the form that TeX recognizes (number "mu" optional plus and minus parts). Alternatively, the dimension, plus and minus parts can be given separately as scaled mu (fixpoint), while $pfill and $mfill are 0 (when the $plus or $minus part is in scaledmu) or 1,2,3 for fil, fill or filll, respectively.
