* algebra/term.spad.pamphlet (is?$OperatorCategory): New.
* algebra/op.spad.pamphlet (BasicOperator): Don't export is? here. Inherit it from OperatorCategory Symbol. * algebra/catdef.spad.pamphlet (LeftLinearSet): New category. (RightLinearSet): Likewise. (LinearSet): Likewise. (AbelianGroup): Extend LeftLinearSet Integer. (LeftModule): Extend LeftLinearSet R. (Module): Extend LinearSet R. (RightModule): Extend RightLinearSet R. * algebra/exposed.lsp.pamphlet: Expose LeftLinearSet, RightLinearSet, and LinearSet. * algebra/Makefile.pamphlet: Tidy.
