+===== Astyle =====
+astyle special usage based on V2.0.4 http://astyle.sourceforge.net/astyle.html
+Example:
+astyle --options=none --align-pointer=name --pad=oper --unpad-paren --pad-paren-out --trim-trailing-whitespace
+--options=none
+    Disable the default options file. Only the command-line  parameters will be used.
+-p, --pad=oper
+    Insert space padding around operators  only. for example: i-j becomes i - j
+-U, --unpad-paren
+    Remove space padding around parenthesis on the inside  and  out‐
+    side. Can be used in combination with the paren padding options.
+    Only padding that has not been requested by other  options  will
+    be removed.
+-d, --pad-paren-out
+      Insert space paddings around parenthesies on the  outside  only.
+      This can be used with unpad=paren to remove unwanted spaces.
+      With -U -d two options, it will be like if (k > 0), not if( k > 0 )
+-k3, --align-pointer=name
+      Attach a pointer or reference operator (*, &, or ^) to the variable name (right).
+      for example: **char* p** becomes **char *p**
+===== Perl/Bash =====
+Use perl to remove trailing whitespace in a string:
+    $str =~ s/\s+$//;
+Take 1 or more white spaces (\s+) till the end of the string ($), and replace them with an empty string.
