--dry-run should give information about what it would do

[machinist]

There is now output about what would happen without --dry-run

Valid. This probably goes along with #21.

You're trying to get me to work during the holidays, right ?

Ok, v0.4.0 (now on PyPI) includes a --verbose option.

Here's me pretending to create version v29.0.0 of bumpversion:

~/workspace/bumpversion git:(master) ○ bumpversion --verbose --dry-run --new-version 29.0.0 major
Reading config file .bumpversion.cfg:
[bumpversion]
files = setup.py bumpversion/__init__.py
commit = True
tag = True
current_version = 0.4.0


Parsing current version '0.4.0' with '(?P<major>\d+)\.(?P<minor>\d+)\.(?P<patch>\d+)'
Parsed the following values: major=0, minor=4, patch=0
Attempting to increment part 'major'
Values are now: major=1, minor=0, patch=0
Available serialization formats: '{major}.{minor}.{patch}'
Found '{major}.{minor}.{patch}' to be a usable serialization format
Selected serialization format '{major}.{minor}.{patch}'
Serialized to '1.0.0'
Dry run active, won't touch any files.
New version will be '29.0.0'
Asserting files setup.py, bumpversion/__init__.py contain string '0.4.0':
Found '0.4.0' in setup.py at line 4:     version='0.4.0',
Found '0.4.0' in bumpversion/__init__.py at line 29: __VERSION__ = '0.4.0'
