Here is the rewritten README for the pulldown-html-ext-cli crate:

A command-line tool for converting Markdown to HTML using the pulldown-html-ext library.

You can install the pulldown-html-ext-cli tool using Cargo:

cargo install pulldown-html-ext-cli

The tool supports several options for converting Markdown to HTML:

pulldown-html-ext-cli [OPTIONS]

• -i, --input <FILE>: Specify the input Markdown file. If omitted, the tool will read from standard input.
• -o, --output <FILE>: Specify the output HTML file. If omitted, the tool will write to standard output.
• -c, --config <FILE>: Provide a TOML configuration file to customize the HTML output.
• -h, --help: Display the help message.
• -V, --version: Print the version information.

To convert a Markdown file to HTML and write the output to stdout:

pulldown-html-ext-cli -i input.md

To convert a Markdown file and write the HTML output to a file:

pulldown-html-ext-cli -i input.md -o output.html

You can provide a TOML configuration file to customize the HTML output. Here's an example configuration:

[html]
escape_html = true
break_on_newline = true
xhtml_style = false
pretty_print = true

[elements.headings]
add_ids = true
id_prefix = "heading-"

[elements.links]
nofollow_external = true
open_external_blank = true

[elements.code_blocks]
default_language = "text"
line_numbers = true

To use the custom configuration, run the tool with the -c option:

pulldown-html-ext-cli -i input.md -o output.html -c custom.toml

For more information on the available configuration options, please refer to the pulldown-html-ext library documentation.
