# # Git Log All
#
# A comprehensive git log analysis tool that generates detailed commit reports
# with time-based filtering and author-specific views. Perfect for reviewing
# development activity across different time periods.
#
# ## Features
# - Time-based commit analysis (day, week, month, year)
# - Author-specific filtering (me/andy, scott/skm)
# - Color-coded output with visual formatting
# - Detailed commit information including messages and file changes
# - Date range reporting with automatic boundary calculation
# - Support for historical analysis (last/one/two/three periods ago)
#
# ## Usage
# ```bash
# git-log-all                        # Current week, all authors
# git-log-all me week                # My commits this week
# git-log-all me month            # Scott's commits this month
# git-log-all day last               # All commits from yesterday
# git-log-all me year two            # My commits from 2 years ago
# ```
#
# ## Time Scopes
# - `day`: Single day analysis
# - `week`: Weekly analysis (default)
# - `month`: Monthly analysis  
# - `year`: Yearly analysis
#
# ## Author Filters
# - `me/mine/andy`: Filter to andy's commits
# - (no filter): Show all authors
#
# ## Offset Options
# - `last/one`: Previous period
# - `two`: Two periods ago
# - `three`: Three periods ago
