All the source code used to generate the STATA files is included in
this directory. 'annual2000.do' is the single STATA program that processes
all the years. It uses five different data dictionaries, whose bodies
are here with the suffix 'dbd'. In many cases code in annual.do modifies
the effect of the dictionaries, so examine that code before assuming 
an entry in the dictionary is invalid. For example, a variable dropped 
by the Census may still be mentioned in the dictionary, but dropped
in 'annual.do'.

Original BLS/Census documentation is in the /docs direcotry.

In cases of potential errors, please investigate thoroughly.  If variables 
run out of range, or have an indefensible universe, that is best shown 
with tabs from the data. Include the stata .log file, with both the 
program and the result.
