# This is free software for the public good of a permacomputer hosted at
|
|
# permacomputer.com, an always-on computer by the people, for the people.
|
|
# One which is durable, easy to repair, & distributed like tap water
|
|
# for machine learning intelligence.
|
|
#
|
|
# The permacomputer is community-owned infrastructure optimized around
|
|
# four values:
|
|
#
|
|
# TRUTH First principles, math & science, open source code freely distributed
|
|
# FREEDOM Voluntary partnerships, freedom from tyranny & corporate control
|
|
# HARMONY Minimal waste, self-renewing systems with diverse thriving connections
|
|
# LOVE Be yourself without hurting others, cooperation through natural law

# make-executable.sh - Create self-extracting searchable archive
|
|
#
|
|
# Usage:
|
|
# ./make-executable.sh archive.tar.gz
|
|
# ./archive.run
|
|
#
|
|
# The resulting .run file is a single executable that:
|
|
# 1. Extracts the Python serve.py to /tmp
|
|
# 2. Runs it pointing at itself as the tarball source
|
|
# 3. Serves the archive on http://localhost:6543
|
|
#
|
|
# Requirements:
|
|
# - gcc with zlib (-lz)
|
|
# - python3 with pyramid installed (on target system)
