+flag                     value
+--------------------     ---------------
+-h, --help, help
+-m, --msg, msg           Quoted text with the msg being added to chat
+-l, --list, list         An integer representing the number of rows you'd like 
+                           to view, default 5
+-b, --block, block       A username to block/ignore
+-u, --unblock, unblock   A username to unblock/unignore
+-c, --channel, channel   Name of the channel you would like to join or create. 
+                           An empty value lists the available channels. 
+-n, --new, new           Check for new, unread messages.
+-N, --new-verbose, new-verbose Check for new, unread messages, creating output
+                         even when no new messages exist.
+
+Channels names ending in ! are private. They can be joined by anyone that 
+knows they exist, but will not be listed in the channel listings. To return
+to the main/default channel, simply switch channels to 'gab':
+    gab channel gab
+
+Examples:
+    gab msg "Good afternoon!"
+    gab list 20
+    gab block annoyingperson
+    gab channel my-secret-channel!
+    gab channel a-public-channel
+    gab unblock somedude
