# extract_nth - Return a subsection of the $file string
#
# the input string looks like this:
# ./build/cbfs/fallback/romstage.elf|fallback/romstage|stage|none||64|--xip*-S*.car.data*-P*0x10000
#
# Sections:
# 1 - Path and name of file [FILENAME: Added to cbfs-files-y list variable]
# 2 - Name of file in cbfs [$(FILENAME)-file]
# 3 - File type: [$(FILENAME)-type]
# bootblock, cbfs header, stage, payload, optionrom, bootsplash, raw, vsa,
# mbi, microcode, fsp, mrc, cmos_default, cmos_layout, spd, mrc_cache,
# mma, efi, deleted, null
# 4 - Compression type [$(FILENAME)-compression]
# none, LZMA
# 5 - Base address [$(FILANAME)-position]
# 6 - Alignment [$(FILENAME)-align]
# 7 - cbfstool flags [$(FILENAME)-options]
#
# Input:
# $(1) = Section to extract
# $(2) = Input string
#
# Steps:
# 1) replace all '|' characters with the sequence '- -' within the full string, prepended and appended with the character '-'
# 2) extract the specified section from the string - this gets us the section surrounded by '-' characters
# 3) remove the leading and trailing '-' characters
# 4) replace all '*' characters with spaces
