SortSRS is a fairly esoteric utility.  It is an add-on for Funduc
Search-Replace.  It tidies *.srs script files by sorting, deduping and
general tidying.  It is only of use to users of the Funduc SR bulk Search
Replace Utility.
It does not handle the *.srx script files used by the more recent SR business edition
which are XML-based.
It is only of use to users of the Funduc SR bulk Search Replace Utility.
Be careful.  Sorting a script may it behave differently since SR
applies the search/replaces in the same order they appear in the *.srs
script file.  Make a backup before using SortSRS in case sorting makes the
script stop working.
It sorts the search/replace pairs by search string, using a
case-insensitive sort, i.e.  interleaving upper and lower case.  It also
sorts and deDups the path items.
To convert a script file, type:
  java.exe -jar C:\com\mindprod\sortsrs\sortsrs.jar myscript.srs
The results replace the old file, so you had better make a backup just in
case this is not what you want.
You can also list several files on the command line:
  java.exe -jar C:\com\mindprod\sortsrs\sortsrs.jar my.srs C:\myscripts\another.srs
DON'T USE WILDCARDS unless you deeply understand how they work.  Windows
expands them, not sortsrs, and feeds them to sortsrs (or any other
program) as a giant list of all the directories and files in the current
directory.  Sortsrs will thus tend process all the files in your
directories, when you just meant to process the files in the current
directory.  Read up on wildcard in the mindprod.com wildcard entry in the
Java glossary.
The -s switch makes all subsequent directories searched recursively to
include all their subdirectories.
e.g.
  java.exe -jar C:\com\mindprod\sortsrs\sortsrs.jar -s E:\env\srscripts
will fix all *.srs files in the E:\env\srscripts directory tree, ignoring
other types of files.
If you have the jar extension set up as executable, you can abbreviate:
  C:\com\mindprod\sortsrs\sortsrs.jar .
If you have C:\com\mindprod\sortsrs on the path, and have set up PATHEXT
to include jar, then you can abbreviate that to:
sortsrs.jar .
If you have Jet, that abbreviates  to
  sortsrs.exe .
You can strip out comments from the scripts with:
  java.exe -jar C:\com\mindprod\sortsrs\sortsrs.jar -strip -s E:\env\srscripts
Favourites are just mini-scripts containing a single search/replace pair,
also stored as *.srs files, but stored in a different directory.  If you
run SortSRS on them, it won't do any harm, and it won't do any good
either.  Since the contain only one item, they are already sorted.
However SortSRS will replace missing lead BOMs, an indicator the file is
UTF-8 encoded even on favourites.
If this utility is of use to you, possibly the CSVToSRS utility part of
the mindprod.com CSV suite may also be of interest.
Beware!  If you edit *.srs scripts outside of Funduc Search/Replace, or if
you generate them programmatically, and you introduce syntax errors,
e.g.  two [Replace] in a row, when you feed them to SR, it will just crash
without any error message.  If you are experimenting, keeps lots of
backups and intermediate backups, so you can compare working and
non-working scripts to see the differences.
I wrote this program without documentation of the SRS file format.  I just
guessed at it by examining examples and doing experiments.  I have
overlooked something, and my program will not handle that feature
correctly.  If you suspect something like that has happened, please email
me the offending script so I can fix immediately fix it.
