+
+========================================
+OVERVIEW
+========================================
+
+minipomodoro is a command-line Pomodoro and time-tracking application.
+It forces users to focus by limiting the number of pauses allowed during a session.
+All data is persisted in a directory called .minipomodoro/
+in the current working directory.
+
+========================================
+COMMANDS
+========================================
+
+--- init ---
+Usage: python minipomodoro.py init
+Creates a .minipomodoro/ directory and an empty timer.dat file.
+If .minipomodoro/ already exists, print "Already initialized" and exit.
+
+--- start ---
+Usage: python minipomodoro.py start "Math Study"
+Starts a new task. Checks if the last completed task was finished less than 5 minutes ago. 
+If so, rejects starting.
+Appends a new task to timer.dat with status RUNNING.
+Prints "Started task: <description>. Focus!"
+
+--- pause ---
+Usage: python minipomodoro.py pause
+Pauses the currently RUNNING task. 
+A user can only pause a task a maximum of 3 times.
+If pause count is 3, prints "Error: Pause limit reached! Keep focusing."
+Otherwise, updates status to PAUSED, increments pause count, and prints "Task paused. <X> pauses remaining."
+
+--- resume ---
+Usage: python minipomodoro.py resume
+Changes the currently PAUSED task status back to RUNNING.
+Prints "Task resumed. Get back to work!"
+
+--- stop ---
+Usage: python minipomodoro.py stop
+Stops the active task and calculates total elapsed time.
+If elapsed time is less than 25 minutes, prints "Warning: Stopped before 25 minutes."
+Marks task as DONE.
+Prints "Task stopped. Total time: <minutes> mins."
+
+--- log ---
+Usage: python minipomodoro.py log
+Prints all tasks, one per line:
+  [1] [DONE] Math Study (25 mins) - 2 pauses
+  [2] [RUNNING] Read Book (12 mins) - 0 pauses
+If no tasks exist, prints "No timer logs found."
+
+========================================
+DATA FORMAT
+========================================
+
+File: .minipomodoro/timer.dat
+Format: One task per line, fields separated by |
+Structure: id | description | status | elapsed_minutes | pause_count | last_update_timestamp
+Example:
+1|Math Study|DONE|25|2|1710345600
+2|Read Book|RUNNING|12|0|1710347800
+
+========================================
+ERROR HANDLING
+========================================
+
+- Running any command before "init": print "Not initialized. Run: python minipomodoro.py init"
+- Starting a task while one is RUNNING: print "Error: A task is already running. Stop or pause it first."
+- Pausing a task that is not RUNNING: print "Error: No active task to pause."
+- Starting a task before 5-minute break: print "Error: You must rest for 5 minutes between tasks."
+- Invalid command: print "Unknown command: <command>"

+
+========================================
+OVERVIEW
+========================================
+
+minipomodoro is a command-line Pomodoro and time-tracking application.
+It forces users to focus by limiting the number of pauses allowed during a session,
+and helps maintain consistency through a daily goal tracking system.
+All data is persisted in a directory called .minipomodoro/
+in the current working directory.
+
+========================================
+COMMANDS
+========================================
+
+--- init ---
+Usage: python minipomodoro.py init
+Creates a .minipomodoro/ directory, an empty timer.dat file, and a default goal.dat file (default value: 0).
+If .minipomodoro/ already exists, print "Already initialized" and exit.
+
+--- goal ---
+Usage: python minipomodoro.py goal <number>
+Sets the daily target for completed tasks. 
+Example: python minipomodoro.py goal 4
+Saves the target integer to goal.dat. 
+Prints: "Daily goal set to <number> tasks. You can do it!"
+
+--- start ---
+Usage: python minipomodoro.py start "Math Study"
+Starts a new task. Checks if the last completed task was finished less than 5 minutes ago. 
+If so, rejects starting.
+Appends a new task to timer.dat with status RUNNING.
+Prints "Started task: <description>. Focus!"
+
+--- pause ---
+Usage: python minipomodoro.py pause
+Pauses the currently RUNNING task. 
+A user can only pause a task a maximum of 3 times.
+If pause count is 3, prints "Error: Pause limit reached! Keep focusing."
+Otherwise, updates status to PAUSED, increments pause count, and prints "Task paused. <X> pauses remaining."
+
+--- resume ---
+Usage: python minipomodoro.py resume
+Changes the currently PAUSED task status back to RUNNING.
+Prints "Task resumed. Get back to work!"
+
+--- stop ---
+Usage: python minipomodoro.py stop
+Stops the active task and calculates total elapsed time.
+If elapsed time is less than 25 minutes, prints "Warning: Stopped before 25 minutes."
+Marks task as DONE.
+Prints "Task stopped. Total time: <formatted_time>."
+
+--- log ---
+Usage: python minipomodoro.py log
+First, checks goal.dat. If a goal > 0 is set, calculates the percentage of DONE tasks and prints a progress bar (10 characters wide, using '=' for progress and ' ' for empty).
+Example: 
+  Progress: [====      ] 2/5 tasks (40%)
+
+Then, prints all tasks, one per line:
+  [1] [DONE] Math Study (25:00) - 2 pauses
+  [2] [RUNNING] Read Book (12:05) - 0 pauses
+If no tasks exist, prints "No timer logs found."
+
+========================================
+DATA FORMAT
+========================================
+
+File: .minipomodoro/timer.dat
+Format: One task per line, fields separated by |
+Structure: id | description | status | elapsed_seconds | pause_count | last_update_timestamp
+Example:
+1|Math Study|DONE|1500|2|1710345600
+2|Read Book|RUNNING|725|0|1710347800
+
+File: .minipomodoro/goal.dat
+Format: A single plain text integer representing the daily task goal.
+Example:
+4
