# 'tagscan' refers to the procedure of examining the CVS data (rlog output
# for each file) and determining what bug IDs exist between two tags.
#
# 'dcuthelp' refers to the procedures of examining the CVS rlog cache
# given a tag and a list of bugs, and helping to incorporate those bug
# fixes into the tag. For this to occur, in each file, any changes after
# tag within the bug list must be contiguous and must begin in the tag's
# revision.

# Params:
# debug - if set, output debugging info
# user - user name
# path_info - override actual path info, for debugging, e.g., "/form"
# mod - module(s) list
# include_attic - if set, include Attic during search (ignored by default)

<P>The search generates a list of all files changes for this bug,
together with the specific revisions in each
file that are relevant (there may be more than one).
<P>In the diff list,
select a <B>file name link</B> to see the CVS log
for that file.
<P>Select a <B>revision link</B> to see changes
checked in against that revision. "Diff" revision links
show diffs against the previous revision. "View" links
show initial check in revisions.
<P>If a file contains more than one revision relevant to this
Jitterbug ID, then an <B>overall revision link</B> will be available.
Use this to see the effect of all changes at once. <I>If the revisions
are not contiguous, then this diff will contain changes
not related to this Jitterbug.</I> In that case you may
prefer to view the individual diffs instead.
<P><B>Incl. Attic</B> causes files under any directory named
"Attic" to be included.
<P><B>Local Diff</B> enables special links that look like this [*]
which cause your browser to download a Windows batch file. The
batch file, when executed, will bring up the relevant diffs in
Compare It!. For this to work, you need the following:
<UL><LI><B>cvs</B> must be on your PATH. For example, you may
add <CODE>C:\\Program Files\\GNU\\WinCVS 1.2</CODE> to your PATH.
<LI><B>wincmp</B> must be on your PATH. This is the Compare It!
executable. For example, you may add <CODE>C:\\Program Files\\Compare
It!</CODE> to your PATH.
<LI>You must be "logged in" for the cvs checkouts to work. If your
name is present in parentheses next to "ICU Jitterbug Diffs" in the
upper left frame, you are logged in.
</UL>
<P><B>Modules</B> lists the modules to be searched. By default
this is "icu icu4j" but any modules (under /usr/cvs) may be listed.
Full module names (e.g., "icu/icuapps") may be used. The following
abbreviations are recognized: <CODE>$x</CODE>.
