+/*
+ * usage:
+ * syn2c slang_shader.syn > slang_shader_syn.h
+ *
+ * when modifying or extending this file, several things must be taken into consideration:
+ * - when adding new operators that were marked as reserved in the initial specification,
+ * one must only uncomment particular lines of code that refer to operators being added;
+ * - when adding new shader target, one must reserve new value for shader_type register and
+ * use it in .if constructs for symbols that are exclusive for that shader;
+ * - some symbols mimic output of other symbols - the best example is the "for" construct:
+ * expression "for (foo(); ; bar())" is seen as "for (foo(); true; bar())" by the output
+ * processor - hence, special care must be taken when rearranging output of essential symbols;
+ * - order of single-quoted tokens does matter in alternatives - so do not parse "<" operator
+ * before "<<" and "<<" before "<<=";
+ * - all double-quoted tokens are internally preprocessed to eliminate problems with parsing
+ * strings that are prefixes of other strings, like "sampler1D" and "sampler1DShadow";
