Actually, as alluded to in this post http://mailman.jach.hawaii.edu/pipermail/perldl/2011-March/004828.html > > An extremely useful starter project to help PDL > would be for a new user to document some index/cross-ref > terms for use in the help/apropos system.

If we had better keywords for the PDL routines, that would greatly improve the results from apropos without any other changes. I gave the example of matrix inversion which was asked about (repeatedly) throughout the perldl list back-issues. My proposal to an interested contributor: (1) Go through *all* the PDL functions, as in 'apropos :' or using Puneets linked list above. (2) Check 'help funcname' and see if the description is clear, useful, and correct (3) Check 'apropos funcname' and other options to see what words can find that funcname. If there are any missing, make a list of the additional keywords for that function. When done, we could use this list of keywords to augment apropos searches to be more useful.
