/*
** Programm-History:
**
** 1.0: initial release
**
** 1.1: needs 3 runs through directories!!!
**
** 1.2: now only 1 run :)
** added possibility to sort entries (using fix arrays of pointers; needs BIIIIG stack)
**
** 2.0: changed sorting; is now performed by linked list/heap (normal stack is enough)
**
** 2.1: new switch: PATZ/S -> using Patz-Font-Output-Strings ( ¬ , ¯ ) instead of " + , ` "
** use prefs-file (ENV:TDir.prefs)
** new switch: NOPREFS/S -> do not read prefs-file
**
** 2.2: use ReadArgs() instead of selfmade parsing; multiple dirs possible now
** tests if dirs exist or not before calling ExamineDir() for the first time
** if no dirs are given, get name of currentdir and display it instead of ""
**
** 2.3: new switch: STAT/S -> print statistic (#dirs,#files) after dir-name
**
** 2.4: if file-/dir-name is too long, end it with "..." before size : file OK, dir i see no chance
** new switch: H=HELP/S prints programname and version
** new switch: N=NOTE/S prints filenote for dirs/files; NOTE: base directory gets no filenote!
**
** 2.5: if file-/dir-name is too long: place "..." in the middle of name (after 5 characters)
**
** 2.6: OutputName() procedure added
**
** 2.7: PutNode()&GetNode() procedures added
**
** 2.8: changed mode lists are ancored: now only one pointer is needed (instead of two/three)
**
** 2.9: replaced printrf() by Printf(); changed 'char tree[]' to 'char *tree[]'
** place "..." in names longer than 24 chars after 'offset' characters now (instead of fixed 5)
** changed default length of filesize from 7 to 8 (filesizes from 10 to 99 MB is reasonable i think)
** restored Printf() to printf() (is needed for OutputName anyway and saved only 2 KB)
**
** 2.10: some code-cleanup
**
