What: Frink
 Where: http://catless.ncl.ac.uk/Programs/Frink/
        ftp://catless.ncl.ac.uk/pub/
 Description: Program to prettify (like the indent command) your Tcl/Tk
        program.  Frink can format, minimize and/or obfuscate your Tcl code.
        It can take some forms of your code and convert it to use message
        catalogs (used for internationalization).  It applies a variety
        of heuristics to the code to try to detect possible errors.
        Supports only vanilla tcl - not extensions such as tclX, itcl, etc.
        Does however recognize namesapce and interp commands.
        Check the first URL on a regular basis for updates.
        Does not permit commercial use.
        Currently at version 2.2.2.

'''Note:''' Be very careful using frink to reformat your source code.
Double check the frink results against the original source.
It messes up your code every once and a while.

Question: What flags do you find most useful when using frink to check for
errors/warnings?

Answer:
 frink -HJ source.tcl
although I sometimes use
 frink -JF FFFFE source.tcl
to turn off a warning for the construct ''variable $varname'' [PT]

[LV] I use frink -J -U -H to give me a LOT of possible issues;
by the time I've checked them all (and I have run the code through
[procheck]), I am ready to move on to looking at algorithm problems...
