TkcxHelp

This program searches for keywords in the help files of Explorer modules. Any number of words may be searched for by entering them (separated by spaces) into the "Keywords" text widget at the bottom of the window. The case of the keywords is ignored by default during searching. Case can be considered by unchecking "Ignore Key Case" in the "Options" menu. Pressing the "Find" button will start the search. The found help files can be viewed by double-clicking on one or by drag-selecting one or more and then pressing "View".

TkcxHelp searches for module help files in the following directories at GFDL:

In order to run TkcxHelp, it is necessary to have two environment variables (TCL_LIBRARY and TK_LIBRARY) set in the calling shell since it was written using the Tcl/Tk language. At GFDL they can be set as:

   setenv TCL_LIBRARY /home/hnv/pub/tcl/tcllib
   setenv TK_LIBRARY /home/hnv/pub/tcl/tklib
then start the program: 
   /home/hnv/explorer/tkcxhelp
You can also just cut and paste the following lines or make them an alias in the shell so that the entire thing runs in the background without modifying the shell's environment. 
   (setenv TCL_LIBRARY /home/hnv/pub/tcl/tcllib; \
    setenv TK_LIBRARY /home/hnv/pub/tcl/tklib; \
    /home/hnv/explorer/tkcxhelp) &
