Perl script to add indentation (leading horizontal space) to LaTeX files. It can modify line breaks before, during and after code blocks; it can perform text wrapping and paragraph line break removal. It can also perform string-based and regex-based substitutions/replacements. The script is customisable through its YAML interface.
