-- SYNOPSIS -- string handling code
--
-- DESCRIPTION
-- Routines to handle string manipulation. This code is not specific
-- to dmake and has/and will be used in other programs. The string
-- "" is considered the NULL string, if NIL(char) is received instead
-- undefined results may occurr. (In reality NIL(char) is checked for
-- but in general it is not safe to assume NIL(char) == NULL)

-- SYNOPSIS -- macro expansion code.
--
-- DESCRIPTION
--
-- This routine handles all the necessary junk that deals with macro
-- expansion. It understands the following syntax. If a macro is
-- not defined it expands to NULL, and {} are synonyms for ().
--
-- $$ - expands to $
-- {{ - expands to {
-- }} - expands to }
-- $A - expands to whatever the macro A is defined as
-- $(AA) - expands to whatever the macro AA is defined as
-- $($(A)) - represents macro indirection
-- <+...+> - get mapped to $(mktmp ...)
--
-- following macro is recognized
--
-- string1{ token_list }string2
--
-- and expands to string1 prepended to each element of token_list and
-- string2 appended to each of the resulting tokens from the first
-- operation. If string2 is of the form above then the result is
-- the cross product of the specified (possibly modified) token_lists.
--
-- The folowing macro modifiers are defined and expanded:
--
-- $(macro:modifier_list:modifier_list:...)
--
-- where modifier_list a combination of:
--
-- D or d - Directory portion of token including separator
-- F or f - File portion of token including suffix
-- B or b - basename portion of token not including suffix
-- T or t - for tokenization
--
-- or a single
-- S or s - pattern substitution (simple)
--
-- NOTE: Modifiers are applied once the macro value has been found.
-- Thus the construct $($(test):s/joe/mary/) is defined and
-- modifies the value of $($(test))
--
-- Also the construct $(m:d:f) is not the same as $(m:df)
-- the first applies d to the value of $(m) and then
-- applies f to the value of that whereas the second form
-- applies df to the value of $(m).
