"""SCons.Tool.linkloc

|
|

|
|
Tool specification for the LinkLoc linker for the Phar Lap ETS embedded
|
||
|
|
operating system.
|
||
|
|
|
||
|
|
There normally shouldn't be any need to import this module directly.
|
||
|
|
It will usually be imported through the generic SCons.Tool.Tool()
|
||
|
|
selection method.
