/*

This routine is to check Harbour source code versions and will work
in conjunction with file "entries.ini" which list the location for
files named "entries" in each CVS-repository sub directory.

To suit with anyone environment, "entries.ini" should be edited to
list the correct locations of files referred to above. To do this,
simply do this as an example :

  C:
  CD\HARBOUR
  DIR entries /s > entries.ini

Then edit as necessary, so "entries.ini" will only consists of file
names with full paths. Once everythings are OK, just issue :

  hversion.exe  [ > version.log ]
