## Usage
The script expects OTA files to be named as follows:
_project_\__device_-ota-_version_-_buildtype_-_incremental_.zip
Full OTA files:
* _project_\__device_-ota-_version_-_buildtype_-_incremental_.zip
Incremental OTA files:
* _project_\__device_-ota-_version_-_buildtype_-_base_\__incremental_.zip
Where:
* _project_ is the project/ROM name, eg. "lineage".
* _device_ is the device name, eg. "mako".
* _version_ is the project/ROM version, eg. "16.0".
* _buildtype_ is the buildtype, eg. "unofficial".
* _base_ is the base incremental version (the starting build).
* _incremental_ is the incremental version, eg. "eng.user.20200807.162000".
The default OTA and target-files file names include all of these fields
@ -33,7 +38,9 @@ except _incremental_. This is the value of `ro.build.version.incremental`
in the system build properties. It is different from `ro.build.date.utc`.
They are __not__ interchangeable.
Example: lineage_mako-ota-16.0-unofficial-eng.user.20200807.162000.zip
Examples:
* lineage_mako-ota-16.0-unofficial-eng.user.20200807.162000.zip
* lineage_mako-ota-16.0-unofficial-eng.user.20200806.162000_eng.user.20200807.162000.zip
The OTA directory may contain subdirectories of arbitrary depth.
