+// : out wip

+
+/*
+I have the following spec, I need you to write a C program that fills this spec:
+
+- this program is called 'wip' and will record 'updates'
+- an 'update' is a line of text with a timestamp
+- this program should use 'argp.h' for processing command line arguments
+- The command line interface has two subcommands, "submit" and "review"
+- submit command:
+  - takes a line of text and writes the timestamp and line of text separated by a tab to a file called 'wip.dat'. This represents one 'update'
+  - the timestamp format should be "%Y-%m-%d %H:%M:%S"
+- review command:
+  - reads the file 'wip.dat' and prints all the updates for the given week.
+  - takes an flag '--period' for determining which week to report updates for
+  - '--period' takes an argument which can be either 'thisweek' or 'lastweek', defaulting to 'thisweek' if not given
+
+
+Here is some example usage:
+
+$ wip submit "This is my update"
+$ wip submit "This is a second update"
+$ wip review
+Updates for this week:
+  + This is my update
+  + This is a second update
+$ wip review -p thisweek
+Updates for this week:
+  + This is my update
+  + This is a second update
+$ wip review --period lastweek
+  + this was an update from last week
