st: log only results of r-class commands

["Dr. Stephen Rothenberg" <srothenberg@mda.cinvestav.mx>]

I am setting up do-files in anticipation of running repetitive descriptive 
statistics for a long-term project.  I will need to produce appendices that 
contain these descriptive statistics, each of which will be scores of pages 
long.

My problem is logging the output of commands like -sum- or -fsum- so I can 
print the appendix stats.  I'd like to produce output that contains only the 
results of the commands in legible tables and my preceding comments that 
identify them, without the tedious chore of editing out the commands 
themselves. The commands run to nearly 400 lines in scattered places 
throughout the log, despite using -bysort- to combine analyses.

Stata includes such commands as -quietly- and the various -set output- 
variations, all of which suppress results output.  The user-supplied 
commands in the -estout- family and others do a great job in producing 
tables of estimation output.  They do not work with descriptive commands, 
which are r-class commands.  Stata allows me to open two logs 
simultaneously, one showing commands, comments, results, and error messages, 
the other showing only the commands, but not only results and comments.

I've searched the FAQs, the ssc contributions, and Statalist, without 
success.

Does anyone know:
1. A way to log only results of r-class commands in presentable tables?
2. If not, can someone provide a method that will do this?
3. If nothing now exists, will StataCorp consider making output only logging 
possible in future releases?
