Thanks to Kit Baum, a new version of the -parmest- package is now available for download from SSC. In Stata, use the -ssc- command to do this, or -adoupdate- if you already have an old version.
The -parmest- package is described as below on my website. The new version fixes a bug, which caused the -label- option to ignore variable labels for X-variables whose corresponding parameters were omitted and set to zero, because these parameters have estimate matrix column names prefixed by "o." This bug caused problems when I used -parmest- under Stata 11 together with my old Stata 10 SSC package -factext-, which uses the parameter X-variable labels to reconstruct factor variables defined using the -xi- command in the -parmest- output dataset.
Fortunately, these problems did not occur in pure Stata 11 programs, which use Stata 11 factor variables (instead of -xi-) in the estimation command, and then use the Stata 11 SSC package -fvregen- (instead of -factext-) to reconstruct these factor variables in the -parmest- output dataset. Unfortunately, I have a lot of old overnight production programs, originally written in Stata 10, which still use -xi- and -factext-, and which caused a panic when they malfunctioned in a mysterious way 2 days ago. Fortunately, the bug is now fixed, and these production programs are now working under Stata 11.

TITLE
parmest: Create datasets with 1 observation per estimated parameter
DESCRIPTION/AUTHOR(S)
The parmest package has 4 modules: parmest, parmby, parmcip and metaparm.
parmest creates an output dataset, with 1 observation per parameter of the
most recent estimation results, and variables corresponding to parameter names,
estimates, standard errors, z- or t-test statistics, P-values, confidence
limits and other parameter attributes. parmby is a quasi-byable extension to
parmest, which calls an estimation command, and creates a new dataset, with 1
observation per parameter if the by() option is unspecified, or 1 observation
per parameter per by-group if the by() option is specified. parmcip inputs
variables containing estimates, standard errors and (optionally) degrees of
freedom, and computes new variables containing confidence intervals and
P-values. metaparm inputs a parmest-type dataset with 1 observation for each
of a set of independently-estimated parameters, and outputs a dataset with
1 observation for each of a set of linear combinations of these parameters,
with confidence intervals and P-values, as for a meta-analysis. The output
datasets created by parmest, parmby or metaparm may be listed to the Stata
log and/or saved to a file and/or retained in memory (overwriting any
pre-existing dataset). The confidence intervals, P-values and other parameter
attributes in the dataset may be listed and/or plotted and/or tabulated.
