Build Tool means it is build the web context folder related to what you have configures in build.xml this xml file make run and with the configured context folders and their respective files are placed in the location where you mentioned in build.xml

Let me tell you a typical scenario,

Let us assume you have changed your database properties, like you have changed the server name or IP address , username , password and you want to re-deploy ur webapplication with these changes in your configuration or property files.Since you will be reading these params from property files or even you have just changed a class file which has the database connection etc etc..

Now you dont need to entirely build the application again. In the ant build.xml you will be specifying some parameters like when you unpack the war file then which folder all the files has be extracted and again when you repack the war file in which folder the output war should be generated.

so when you run it, all the files will be unpacked a folder and after that copy ur changed file and run the command to repack it and the updated war file with the changes will be created. then you can again redeploy the application with minimal effort

I hope u understood.

All the IDE's like eclipse, netbeans , and wsad generates these build.xml files in the project folder itself.
