If I read that correctly, it doesn't even require that the log entries be in date/time order. Is that so?
that's right - this's not necessary. On the flip side, however, the output will be in unsorted, random, unspecified order. The latter, can be easily fixed (if necessary - assuming the INCOMING order is temporal).

NAME
doctools::cvs - Processing text in 'cvs log' format
SYNOPSIS
package require Tcl 8.2
package require textutil
package require doctools::cvs ?1?
::doctools::cvs::scanLog text evar cvar fvar
::doctools::cvs::toChangeLog evar cvar fvar
_________________________________________________________________
DESCRIPTION
This package provides Tcl commands for the processing and reformatting text in the format generated by the cvs log command.
The commands ::doctools::cvs::scanLog and ::doctools::cvs::toChangeLog are derived from code found on the Tcl'ers Wiki
[http://wiki.tcl.tk]. See the references at the end of the page.
API
::doctools::cvs::scanLog text evar cvar fvar
The command takes the text and parses it under the assumption that it contains a CVS log as generated by cvs log. The resulting
information is stored in the variables whose names were specified via evar, cvar, and fvar.
Already existing information in the referenced variables is preserved, allowing the caller to merge data from multiple logs into one
database.
varname evar (in)
Has to refer to a scalar variable. After the call this variable will contain a list of all the entries found in the log file.
An entry is identified through the combination of date and author, and can be split over multiple physical entries, one per
touched file.
It should be noted that the entries are listed in the same order as they were found in the text. This is not necessarily
sorted by date or author.
Each item in the list is a list containing two elements, the date of the entry, and its author, in this order. The date is
formatted as year/month/day.
varname cvar (in)
Has to refer to an array variable. Keys are strings containing the date and author of log entries, in this order, separated
by a comma.
The values are lists of comments made for the entry.
varname fvar (in)
Has to refer to an array variable. Keys are strings containing date, author of a log entry, and a comment for that entry, in
this order, separated by commas.
The values are lists of the files the entry is touching.
::doctools::cvs::toChangeLog evar cvar fvar
] The three arguments for this command are the same as the last three arguments of the command ::doctools::cvs::scanLog. This com-
mand however expects them to be filled with information about one or more logs. It takes this information and converts it into a
text in the format of a ChangeLog as accepted and generated by emacs. The constructed text is returned as the result of the command.
