Short: "Generate markdown documentation from directory structure",
Long: `dirmd walks a directory and generates a markdown file with:
- Directory tree structure
- All readable text files with their contents
Examples:
# Create new documentation
dirmd -o output.md ~/repos/myproject
# Append a single file
dirmd -a -i README.md -o existing.md
# Append another directory
dirmd -a -o existing.md ~/repos/anotherproject`,
