# This is not a independent Makefile; it is auxiliary file

# included from main Makefile.

# It depends on the following variables and macro:

# $(FASM_PROGRAMS) is a list of all programs to build with FASM rule;

# $(binarypart) is a macro which converts from $(1)=item of $(FASM_PROGRAMS)

# to space-escaped full name of binary, $(respace) unescapes spaces;

# $(fbinary) and $(fsource) gives space-unescaped full name of binary

# and source (respectively) of $(f)=item of $(FASM_PROGRAMS).

# Define the rule for all FASM programs.

# Yes, this looks like a black magic.

# But it is not so scary as it seems.

# First, we define "meta-rule" as a rule which is

# macro depending on $(fasmprog).

# Second, the construction foreach+eval creates

# usual rules, one for each $(fasmprog) in $(FASM_PROGRAMS).

# Note that meta-rule is double-expanded, first

# time as the arg of eval - it is the place where $(fasmprog)

# gets expanded - and second time as the rule;

# so all $ which are expected to expand at the second time should be escaped.

# And all $ which are expected to be expanded by the shell should be escaped

# twice, so they become $$$$.

# The arguments of macro fasm_meta_rule:

# $(1) = name of binary file,

# $(2) = name of main source file.

# $(3) = folder of binary file - without spaces.

# $(4) = name of program - without path and extension,
