Use separate arguments for tuple-valued CLI options.

-c and -w require separate values. Use -c pkg1 pkg2 and -w pkg1 2.0 -w pkg2 1.5. The documented -s option, benchmark options, manager keyword, and PackageMaximizer.solve_with_weights exist.

tuple-valued options as separate arguments: use “-c pkg1 pkg2” and repeated “-w
pkg1 2.0 -w pkg2 1.5” forms, while preserving the existing documented -s example

### Пример 2: Использование в коде Python
```python
from package_maximizer import PackageMaximizer, Package

# Создание пакетов
pkg1 = Package(name="nginx", version="1.25.0")
pkg2 = Package(name="apache2", version="2.4.57")
pkg3 = Package(name="postgresql", version="15.0")

# Добавление конфликтов
pkg1.conflicts = ["apache2"] # nginx конфликтует с apache2

# Создание максимайзера
maximizer = PackageMaximizer(manager="apt", solver="z3")

# Решение
result = maximizer.maximize([pkg1, pkg2, pkg3])
print(f"Выбранные пакеты: {[p.name for p in result]}")
# Вывод: Выбранные пакеты: ['nginx', 'postgresql']

The documented output is not guaranteed.

Only one of nginx and apache2 can be selected, and both choices give the same maximum count. A solver may return ['apache2', 'postgresql']. The greedy fallback sorts by name and selects apache2 first. Present the output as one possible result, or use an example where the optimum is unique.

📝 Proposed wording 
 print(f"Выбранные пакеты: {[p.name for p in result]}")
-# Вывод: Выбранные пакеты: ['nginx', 'postgresql']
+# Возможный вывод: Выбранные пакеты: ['nginx', 'postgresql']
+# (nginx и apache2 взаимоисключающие, поэтому солвер может выбрать apache2)

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

In `@README.md` around lines 60 - 61, Update the README example around the
selected package output to avoid implying a guaranteed package list: either
label the shown list as one possible result or replace it with an input whose
optimal selection is unique, while preserving the demonstrated output format.

```

### Пример 3: Использование с весами
```python
from package_maximizer import PackageMaximizer, Package

# Пакеты с разными приоритетами
packages = [
Package(name="python3", version="3.11"),
Package(name="python3-dev", version="3.11"),
Package(name="build-essential", version="12.9"),
]

# Веса (python3-dev важнее)
weights = {
"python3": 1.0,
"python3-dev": 2.0,
"build-essential": 1.5
}

maximizer = PackageMaximizer(solver="z3")
result = maximizer.solve_with_weights(packages, weights)
print(f"Выбранные пакеты: {result}")
```

### Пример 4: Бенчмаркинг солверов
```bash
# Сравнить производительность солверов
package-maximizer benchmark --solvers greedy,z3,pulp --packages 100 --runs 5
```

setuptools_scm fallback_version dynamic project version pyproject.toml official documentation

💡 Result:

To use setuptools_scm with a dynamic version and a fallback version, you must configure your pyproject.toml to handle dynamic metadata and specify the fallback behavior within the [tool.setuptools_scm] section [1][2]. 1. Dynamic Version Configuration In your pyproject.toml, you must indicate that the project version is dynamic. This informs the build backend that the version will be determined at build time rather than being hardcoded in the file [3][2]. [project] name = "your-package" dynamic = ["version"] 2. Fallback Version Configuration The fallback_version parameter is used to provide a version string if setuptools_scm cannot detect the version via SCM metadata (e.g., when building from a source archive, such as a tarball, that lacks metadata) [1][4][5]. By default, if this is not set, setuptools_scm will raise an error if version detection fails [1][6]. You can define this in the [tool.setuptools_scm] table [2]: [tool.setuptools_scm] fallback_version = "0.1.0" Summary of Requirements - Build System: Ensure setuptools and setuptools-scm are defined in your [build-system] requires [7][2]. - Configuration: All non-code configuration (like fallback_version) should reside in pyproject.toml [7][8]. Use a setup.py file only if you need to pass Python callables (e.g., custom version schemes) that cannot be expressed in TOML [7][8]. For additional stability, especially when building from archives that do not contain SCM metadata, ensure your build environment is correctly configured to support these settings [7].

Citations:

Update the distribution fallback version.

pyproject.toml uses setuptools_scm with fallback_version = "0.1.0". When SCM metadata is unavailable, distribution metadata can report 0.1.0 while package_maximizer.__version__ reports 0.2.0. Set the fallback to 0.2.0.

In `@package_maximizer/__init__.py` at line 7, Update the setuptools_scm
fallback_version configuration to 0.2.0 so it matches
package_maximizer.__version__ when SCM metadata is unavailable.
