Ado-file lines that start with *! are echoed by the -which- command, primarily 
to allow for easy version identification.
Typically, programmers will include in their ado-files such a line with, at 
minimum, the (external) version number for the ado and the program 
version/revision date.
However, any line included in the ado that starts with *! in the first two 
columns will be displayed by -which-.
Eg. if -hprescott- has been installed:
  . which hprescott
  f:\ado\stbplus\h\hprescott.ado
  *! hprescott 1.0.7 CFBaum  01aug2006

Hi, can someone tell me the purpose of appending ! to the comment
indicator at the start of an ado file such as :
. ssc type hprescott.ado
*! hprescott 1.0.7 CFBaum  01aug2006
*  from hprescott(8).ado 1.0.4  18jun2006
remaining output cut off
Thanks.
