Yupa is a CLI browser for Gopher and Gemini protocols.

A successor to gmi100 [1][2] which has crazy source code because was
made for fun but I found it approach to browsing text protocols very
appealing.  I kept using gmi100 despite having "better" alternatives.
This is how Yupa was born.  It's essentially gmi100 interface but with
normal source code, support for Gopher and Gemini protocols and few
more features.

Build and run:

	$ ./build       # Compile yupa binary
	$ ./yupa -h     # Print usage instruction
	$ ./yupa URI    # Run with optional URI
	$ ./yupa h      # Run with help command

Usage:

	$ ./yupa		# Start Yupa
	gemini://tilde.pink	# Load page with absolute URI

	# After page is loaded the YUPAPAGER (`less` by default) is
	# used to display it.  When you are done reading the page and
	# you want to insert another Yupa command you have to first
	# quit the pager.  In case of less it's done by inserting `q`.

	l	# Inspect all page links
	l81	# Inspect specific page link
	81	# Visit page link
	b	# Go back in browsing history
	f	# Go forward in browsing history
	h	# Print help message with list of commands
	q	# Quit
