category Package
shortdesc Redefine symbols where names conflict.
longdesc There are a number of symbols (e.g., \Square) that are defined by
longdesc multiple packages.  In order to typeset all the variants in a
longdesc document, we have to give the glyph a unique name.  To do that, we
longdesc define \savesymbol{XXX}, which renames a symbol from \XXX to
longdesc \origXXX, and \restoresymbols{yyy}{XXX}, which renames \origXXX
longdesc back to \XXX and defines a new command, \yyyXXX, which corresponds
longdesc to the most recently loaded version of \XXX. [description copied
longdesc from TeX Catalogue]
