# Download NLTK data packages directly from GitHub, bypassing Python.
|
|
# Avoids CPU-instruction failures (SIGILL) on older hardware lacking AVX.

|
|
# Intended for use during Docker image build only.

# Environment:
|
|
# NLTK_DATA - Target directory for NLTK data (default: /usr/share/nltk_data)
|
|
#
|
|
# Returns: 0 on success, non-zero if any package failed
