-    * MACRO:		strictly a macro (may never become a inline func)

-mhl/memory.h:	Memory management functions
-
-    * mhl_mem_alloc_u(sz)				[MACRO-FUNC]
-    
-	Allocate sz bytes on stack, unitialized
-
-    * mhl_mem_alloc_z(sz)				[INLINE-FUNC]
-
-	Allocate sz bytes on stack, zero'ed
-
-    * mhl_mem_free(ptr)					[INLINE-FUNC]
-
-	Free chunk @ptr (MUST be allocated w/ mhl_mem_alloc_*()),
-	passing NULL is graciously allowed
-
-    * mhl_mem_realloc(ptr,newsize) -> returns newptr
-    
-	Re-allocates a heap chunk, just like realloc()
-
-    * MHL_PTR_FREE(ptr)					[MACRO-ONLY]
-    
-	like mhl_mem_free(), but with ptr as a variable that gets cleared
-	(use this as shortcut to "mhl_mem_free(foo); foo = NULL")
-
-mhl/string.h:	String helpers
-
-    * mhl_str_dup(const char*s) -> char*
-
-	[MACRO-FUNC] Safe version of strdup(), when NULL passed, returns strdup("")
-
-    * mhl_str_ndup(const char* s) -> char*
-
-	[MACRO-FUNC] Safe version of strndup(), when NULL passed, returns strdup("")
-
-    * mhl_str_trim(char* s) -> char*
-
-	[INLINE-FUNC] Trims the string (removing leading and trailing whitespacs), 
-	WITHIN the passed buffer, returning the string s itself.
-	When NULL passed returns NULL.
-
-    * mhl_str_toupper(char* s) -> char*
-
-	[INLINE-FUNC] Converts the string in passed buffer to uppercase, returns that
-	buffer. When NULL passed returns NULL.
-
-    * mhl_str_concat_1(const char* base, const char* one) -> char*
-
-	[INLINE-FUNC] Concatenates the string one onto the string base and returns the
-	result in a newly allocated buffer (free it w/ mhl_mem_free()).
-	For NULL strings, "" is assumed.
-
-    * mhl_str_concat_2(const char* base,const char* one,const char* two) -> char*

-
-    * mhl_str_reverse(char* str)	-> char*
-    
-	[INLINE-FUNC] Reverses the string in passed buffer and returns the buffer ptr itself.
-	If NULL is passed, returns NULL.
-
-mhl/escape.h:	Shell-style string escaping
-
-    * mhl_shell_escape_toesc(char c) 	-> bool
-
-	[MACRO-FUNC] returns true when given char has to be escaped
-
-    * mhl_shell_escape_nottoesc(char c)	-> bool
-
-	[MACRO-FUNC] opposite of mhl_shell_escape_toesc()
-
-    * mhl_shell_escape_dup(const char* s) -> char*
-
-	[INLINE-FUNC] escapes an string and returns the result in a malloc()'ed chunk
-	Passing NULL returns an empty malloc()ed string.
-
-    * mhl_shell_unescape_buf(char* s) -> char*
-
-	[INLINE-FUNC] unescapes the string into given buffer (changes buffer!) and 
-	returns ptr to the buffer itself. When NULL passed returns NULL.
-
-mhl/env.h:	Environment variable helpers
-
-    * mhl_getenv_dup(const char* n)	-> char*
