INTROOT is an installation area with the same structure as ACSROOT, but the main difference is that it allows to install code without interfering with the ACS (or your project installation). It is very handy for development and experimental tests and also as a patching system, specially when used in combination with INTLIST. INTLIST is just a list of INTROOTs, which have an order of prioritization which will be used to choose binaries, libraries, jars, python code, etc. from one place or another. Everything that is in two or more INTROOTs gets hiden hidden for the lower priority one by the one with highest priority.
