{title:Description}

{pstd}
{cmd:webdescribe} produces a summary of the Stata-format dataset located by
appending {it:filename} to the URL.

{pstd}
When setting {it:URL}, you can specify just the name of the web site,
but it will not produce an error if you prepend {cmd:http://} or if you
append the trailing slash.

{pstd}
Using {cmd:webdescribe set} {it:URL} enables you to describe multiple
datasets from the same URL without having to specify the URL each time.
This is a convenience command that simply calls {helpb describe} with
the appropriate option to describe a file located at URL.  The two
examples below are equivalent.

{pstd}
The name, storage type, display format, value label, and variable label
for each variable along with summary information about the dataset are
displayed by default.


{title:Options}

{dlgtab:Main}

{phang}
{opt short} displays only the summary information about the dataset:
number of observations, number of variables, size, sort order, dataset
label, and the time the file was last saved.

{phang} 
{opt varlist}, an option for programmers, specifies that, in addition to the
usual saved results, {cmd:r(varlist)} and {cmd:r(sortlist)} also be saved.
{cmd:r(varlist)} contains the names of the variables in the dataset.
{cmd:r(sortlist)} contains the names of the variables by which the data
are sorted.
