```

## Usage

```
rmcm [OPTIONS] [FILES]...

Arguments:
  [FILES]...  Input files to process (if empty, reads from stdin)

Options:
  -l, --language <LANG>           Specify language (required for stdin, optional for files)
  -i, --in-place                  Modify files in-place instead of outputting to stdout
  -c, --collapse-whitespace <N>   Collapse consecutive blank lines to at most N blank lines
  -f, --force                     Continue processing even if some files fail
  -h, --help                      Print help
```

## Examples

```bash
# remove comments from a python file and print to stdout
rmcm script.py

# remove comments and modify file in-place
rmcm -i main.rs

# process multiple files in-place
rmcm -i *.js

# read from stdin (language must be specified)
cat script.py | rmcm -l python

# collapse multiple blank lines to at most 1
rmcm -c 1 -i code.js

# override language detection
rmcm -l python file.txt

# continue processing even if some files fail
rmcm -f -i *.rs
```

## TODO

Want to help? Here's what we're planning:
- [ ] **SQL** - Add support for SQL dialects with `--` and `/* */`
- [ ] **Perl** - Support `#` comments and POD documentation
- [ ] **R** - Handle `#` comments
- [ ] **Kotlin** - Support `//` and `/* */` comments
- [ ] **Dart** - Add comment support
- [ ] **Elixir** - Handle `#` comments
- [ ] **Configuration files** - `.ini`, `.conf`, `.env`, `.toml`
- [ ] **Documentation generation** - Option to extract comments instead of removing
- [ ] **Preserve specific comments** - Keep comments matching patterns (e.g., license headers)
- [ ] **Recursive directory processing** - Process entire directory trees
- [ ] **Parallel processing** - Speed up batch operations
