# Perform final actions for new version release:
update : version_update tclIndex

# _simple rule_
# Replace old version number with new in relevant files:

# After manual inspection of line-wrapped markdown files, overwrite originals
# with edited files:
doc_margin_final : %.md.fold.md :: doc/%.md.fold.md README.md.fold.md
	file copy -force $< [file root [file root $<]]
	file delete $<

# _reverse pattern match rule_
# Wrap markdown files to 80-char line width.
# Redirect to new file for manual inspection:
doc_margin_draft : %.md :: doc/%.md README.md
	exec fold -s $< > $<.fold.md
	
# _procedure_
# Simple proc to replace a string in a file:

	set conts [read $f]
	close $f
	
	set conts [string map [list $oldString $newString] $conts]
