 In general, if you aren't a decent developer, they aren't much good.

 $ file core

 will tell you what program made it.

 $ gdb 
 (gdb) core core
<gdb will print stuff to tell you it's loading the core file>
 (gdb) where
<gdb will print what functions it called, before it crashed>

 If you have compiled the program with -g , you can tell what line in the
program you crashed at & stuff, with "where". Typing "list" will list the
source code at the part it crashed at.
