##
## Gathers information about SDK and board packages. Also collects
## info about actual build deps of board packages, which may be useful
## for verifying if SDK provides those.
##
## Reports generated:
## sdk-pkgs - contains package information for SDK
## sdk-pkgs-kv - contains package information with key values (USE, PYTHON_TARGETS, CPU_FLAGS_X86) for SDK
## board-pkgs - contains package information for board for chosen architecture
## board-bdeps - contains package information with key values (USE, PYTHON_TARGETS, CPU_FLAGS_X86) of board build dependencies
## sdk-profiles - contains a list of profiles used by the SDK, in evaluation order
## board-profiles - contains a list of profiles used by the board for the chosen architecture, in evaluation order
## sdk-package-repos - contains package information with their repos for SDK
## board-package-repos - contains package information with their repos for board
## sdk-emerge-output - contains raw emerge output for SDK being a base for other reports
## board-emerge-output - contains raw emerge output for board being a base for other reports
## sdk-emerge-output-filtered - contains only lines with package information for SDK
## board-emerge-output-filtered - contains only lines with package information for board
## sdk-emerge-output-junk - contains only junk lines for SDK
## board-emerge-output-junk - contains only junk lines for board
## *-warnings - warnings printed by emerge or other tools
##
## Parameters:
## -h: this help
##
## Positional:
## 1 - architecture (amd64 or arm64)
## 2 - reports directory
