You can put two documentation driver files in the dtx file and
process both, e.g.:
1. tex mypackage.ins
   unpacks mypackage-foo.drv and mypackage-bar.drv,
   and other files like mypackage-foo.sty, mypackage-bar.sty.
2. pdflatex mypackage-foo.drv
   generates mypackage-foo.pdf
3. pdflatex mypackage-bar.drv
   generates mypackage-bar.pdf
