-@section Introduction to @command{gcov-tool}
-@c man begin DESCRIPTION
-
-@command{gcov-tool} is an offline tool to process gcc's gcda profile files.
-
-Current gcov-tool supports the following functionalities:
-
-@itemize @bullet
-@item
-merge two sets of profiles with weights.
-
-@item
-read a stream of profiles with associated filenames and merge it with a set of
-profiles with weights.
-
-@item
-read one set of profile and rewrite profile contents. One can scale or
-normalize the count values.
-@end itemize
-
-Examples of the use cases for this tool are:
-@itemize @bullet
-@item
-Collect the profiles for different set of inputs, and use this tool to merge
-them. One can specify the weight to factor in the relative importance of
-each input.
-
-@item
-Collect profiles from target systems without a filesystem (freestanding
-environments).  Merge the collected profiles with associated profiles
-present on the host system.  One can specify the weight to factor in the
-relative importance of each input.
-
-@item
-Rewrite the profile after removing a subset of the gcda files, while maintaining
-the consistency of the summary and the histogram.
-
-@item
-It can also be used to debug or libgcov code as the tools shares the majority
-code as the runtime library.
-@end itemize
-
-Note that for the merging operation, this profile generated offline may
-contain slight different values from the online merged profile. Here are
-a list of typical differences:
-
-@itemize @bullet
-@item
-histogram difference: This offline tool recomputes the histogram after merging
-the counters. The resulting histogram, therefore, is precise. The online
-merging does not have this capability -- the histogram is merged from two
-histograms and the result is an approximation.
-
-@item
-summary checksum difference: Summary checksum uses a CRC32 operation. The value
-depends on the link list order of gcov-info objects. This order is different in
-gcov-tool from that in the online merge. It's expected to have different
-summary checksums. It does not really matter as the compiler does not use this
-checksum anywhere.
-
-@item
-value profile counter values difference: Some counter values for value profile
-are runtime dependent, like heap addresses. It's normal to see some difference
-in these kind of counters.

-
-@item merge
-Merge two profile directories.
-@table @gcctabopt
-
-@item -o @var{directory}
-@itemx --output @var{directory}
-Set the output profile directory. Default output directory name is
-@var{merged_profile}.

-respectively. The default weights are 1 for both.
-@end table

-
-For the generation of a @emph{gcfn} and @emph{gcda} data stream on the target
-system, please have a look at the @code{__gcov_filename_to_gcfn()} and
