Should someone be able to publicly request a correction in someone else's package 
when it clearly does not affect that person? Is there a gross scientific falsehood 
not consistent with good research? Have I caused an unconscionable loss or damages
to someone as a result of my package? Did I steal codes out of someone's programs 
and misrepresented myself as the author?
 
I am trying to understand Austin's position here.
 
What it says in the help file is not important to me.
 
If Austin thinks it will greatly improve the package, then I am open to a revision. 
He can post a revised version help file here or send it to me privately.
 
The current version says the following:

    distmatch provides a fast and easy way to perform distance matching based
    on latitudes and longitudes. It mathces location identifiers, attributes,
    or distances from one to another. It also counts the number of
    neighboring locations within a given area, either in circles or bands of
    concentric circles.
 
    Outputs produced by distmatch are typically used in studies of geocoded
    data. These outputs can also be produced by non-Stata softwares such as
    ArcGIS and ArcView.
 
    distmatch implements haversine formula for distance. The default is in
    miles.
 
    Distance matching is computationally intensive. Observations of 3,000 may
    take several minutes to complete.  Other methods typically take days if
    not weeks and requires extensive user-involvement.
