/*
   Scanner for the HDF-EOS StructMetadata attribute.  This file works with
   gnu's flex scanner generator. It returns either ATTR, ID, VAL, TYPE or
   one of the single character tokens `{', `}', `;', `,' or `\n' as integers.
   In the case of an ID or VAL, the scanner stores a pointer to the lexeme
   in yylval (whose type is char *).

   The scanner discards all comment text.

   The scanner returns quoted strings as VALs. Any characters may appear in a
   quoted string except backslash (\) and quote("). To include these escape
   them with a backslash.
   
   The scanner is not reentrant, but can share name spaces with other
   scanners.
   
   Note:
   1) The `defines' file he5dds.tab.h is built using `bison -d'.
   2) Define YY_DECL such that the scanner is called `he5ddslex'.
   3) When bison builds the he5dds.tab.h file, it uses `he5dds' instead of `yy' for
   variable name prefixes (e.g., yylval --> he5ddslval).
   4) The quote stuff is very complicated because we want backslash (\)
   escapes to work and because we want line counts to work too. In order to
   properly scan a quoted string two C functions are used: one to remove the
   escape characters from escape sequences and one to remove the trailing
   quote on the end of the string.
