Where can I download Arduino 0017 RC2. You refer to the home page of the Arduino project but I have as of yet not been able to locate it this RC.
A link was published on the Arduino Developers mailing list. You could check the archives.
Where is the general configuration file kept and is it editable by a human (hex editors don't count)
Humans should use the command-interface I have build into the tool. The trick is that only the java runtime knows where the file is, and I don't have to care where that file is on linux/windows/whatever
Will it work with the Arduino bootloader? Your wiki only mentions the use of an external programmer.
Works with the bootloader too. Seehttp://code.google.com/p/angbt/wiki/AngCommandBasics
or use java -jar ang.jar help upload
the build-in help has a topic
I'd like to set the type of target just once and have parameters such as programmer and connection type as things I can keep in a custom configuration file. Something like an angbtrc file in the current project directory, or something. That way a call to "java -jar ang.jar upload" or "java -jar ang.jar compile" in the CWD would be sufficient.
Every setting is reachable on the commandline. With emacs I set the default compile command bound to F8. If I had to do something more complicated I'd run the tool-comands from an ant-target, makefile, bash-script or bat-file, whatever is easiest in your environment.
