  ## Then get the names

## This function will translate the from the actual mappings to the requisite

## humans etc.

## ALSO problematic: CHRLENGTHS.Rd, GO2ALLEGS.Rd UCSCGENES.Rd

## the manList when I call createPackage.

  file.copy(from = dir(originDir, full.names = TRUE),
            to = tdir,
            recursive = TRUE)
  
  ## Then unlink unwanted man pages from tdir
  manDir <- file.path(tdir, "man")
  manFiles <- dir(manDir)
  rmFiles <- manFiles[!(manFiles %in% manList)]
  rmFiles <- file.path(manDir, rmFiles)

  ## Then remove our terrible temp dir
