[Boost-build] rules/actions not being invoked as expected

Hi all,

I have a jamfile that defines some custom rules for compiling bison and 
lex files.

I have taken the default bison.jam and lex.jam files, renamed them to 
protect the innocent(lets say mybison.jam and mylex.jam), changed the 
generator line to reflect the change in file name and added the 
appropriate non standard things that need doing in the actions for each.

This works great if you are in the same directory as the Jamfile that 
invokes the rules.  If I am in another project(Jamfile) that depends on 
this project(Jamfile) it seems the default rules for bison and lex kick 
in and mine are ignored.

I have using statements for mybison.jam and mylex.jam in my project- 
root.jam file at the top of the tree.

so can any one clue me in as to how I make my lex and bison generators 
the only ones to be used for a particular Jamfile so any dependant 
Jamfiles will correctly invoke my generators?

thanks
malcolm
