So, where does all the work from above go.
Adding support for an xtYYY device:
o) Take the rsd xml script from the FXZ for the particular device and copy it to FULL_xtYYY.xml in the rsd_scripts directory
o) Take the rsd xml script from the FXZ for the particular device and copy it to KEEP-DATA_xtYYY.xml in the rsd_scripts directory
o) Edit KEEP-DATA_xtYYY.xml, remove erase data lines
o) Create new FULL_xtYYY.bat and/or FULL_xtYYY.sh in the fastboot_scripts directory
o) Edit FULL_xtYYY.bat and/or FULL_xtYYY.sh to add fastboot flash lines for each line in the FULL_xtYYY.xml script
o) Create new KEEP-DATA_xtYYY.bat and/or KEEP-DATA_xtYYY.sh in the fastboot_scripts directory
o) Edit FULL_xtYYY.bat and/or KEEP-DATA_xtYYY.sh to add fastboot flash lines for each line in the KEEP-DATA_xtYYY.xml script
o) Add any custom scripts required by the end user...name FUNCTION_xtYYY.xml and FUNCTION_xtYYY.bat and/or FUNCTION_xtYYY.sh in the respective rsd_scripts and fastboot_scripts directories
