Examples:
 sbomqs compliance --bsi|--oct  [--basic|--json] <SBOM file>

  # Check a BSI TR-03183-2 v1.1 compliance against a SBOM in a table output
  sbomqs compliance --bsi samples/sbomqs-spdx-syft.json

  # Check a BSI TR-03183-2 v1.1 compliance against a SBOM in a JSON output
  sbomqs compliance --bsi --json samples/sbomqs-spdx-syft.json

  # Check a OpenChainTelco compliance against a SBOM in a table output
  sbomqs compliance --oct samples/sbomqs-spdx-syft.json

  # Check a OpenChainTelco compliance against a SBOM in a JSON output
  sbomqs compliance --oct --json samples/sbomqs-spdx-syft.json


Flags:
  -b, --basic      output in basic format
  -c, --bsi        BSI TR-03183-2 v1.1 compliance
  -D, --debug      enable debug logging

$ go run main.go score -h       
     
comprehensive quality score for your sbom

sbomqs score [flags]

Examples:
sbomqs score [--category <category>] [--feature <feature>]  [--basic|--json]  <SBOM file>

# Get a score against a SBOM in a table output
sbomqs score samples/sbomqs-spdx-syft.json

# Get a score against a SBOM in a basic output
sbomqs score --basic samples/sbomqs-spdx-syft.json

# Get a score against a SBOM in a JSON output
sbomqs score --json samples/sbomqs-spdx-syft.json

# Get a score for a 'NTIA-minimum-elements' category against a SBOM in a table output
sbomqs score --category NTIA-minimum-elements samples/sbomqs-spdx-syft.json

# Get a score for a 'NTIA-minimum-elements' category and 'sbom_authors' feature against a SBOM in a table output
sbomqs score --category NTIA-minimum-elements --feature sbom_authors samples/sbomqs-spdx-syft.json


Flags:
-b, --basic               results in single line format
