Hi all.

Does any one know of a [trick | anttask] that allows to check a path, meaning that each elements of a path is valid ?
I think this would be really useful to debug ant scripts : In an "init" target, it could allow to check all ${xxx.jar}, ${xxx.dir}, ${xxx.classpath} before starting building anything.

Spec :
For a directory or a file, it would check that the dir or the file exists ; for a fileset, it would check that all patterns in the fileset refer to at least an existing file or an existing directory.

Hi all,

What's the use of that weird ":mode=ant" comment on line 1 of the properties.xml and taskdef.xml of the book's source files ?
What program or task uses this (meta-?)markup ?
