+/* I actually intend to use this in 32 bit programs, unlike the other stuff
+ in this lib. IMHO GNU getline is broken. It is too hard to use.
+
+ Just pass this function a FILE * and it will retrieve a line for you using
+ getc(). It will realloc() exactly the amount of memory needed, and will
+ generate error messages for non-ascii characters on stderr.
+
+ This may not be your ideal. It probably generates far too many errors.
+ It doesn't work well for those who don't use English (but since
+ Linux-less-than-32 libc and kernels are each being produced by one
+ person in the US and one in the UK, this isn't a problem). It probably
+ is not what you (or I) want for interactive input.
+
+ You're welcome to modify this routine to meet your needs. However, if
+ you change the semantics significantly, please change the name.
+
+ (Maybe I should have put my own name on it so there will be no confusion
+ about who thought it was ideal). */
