# mduem - Little utility for little software development
#
# This is a library Makefile to maintain software development, especially for
# Vim script.  Note that this Makefile requires GNU make to use.
# Coding Rules  #{{{1
#
# - Use non-empty string as true and empty string as false.
#
#
# Naming Rules:
#
# - Use UPPER_CASE variables to be configured by user.
#
# - Use lower_case variables for internal use of mduem.
#
# - Use suffix "_p" to indicate that a boolean value is resulted from
#   a variable.
#   Example: SHOULD_INSTALL_ASIS_P
#
# - Use noun for ordinary variables.
#   Example: repos_name, TARGETS_GENERATED
#
# - Use verb for variables as functions.
#   Example: resolve_dep_uri, RENAME_TARGET
#
# - Use prefix "generate_rule_" for variables to generate make rules.
#   Example: generate_rule_to_install_a_target
#
# - Use abbreviations for words which names are too long to code.
#   Example: dependency => dep, directory => dir, repository => repos
#
# - Use lower-case names for phony targets.
#
# - Use verb for phony targets.
#   Example: clean, install, pack, ...
#
# - Use hyphens to join words in names of phony targets.
#   Example: clean-junks, fetch-deps
#
# - Use prefix "," for names of files which are automatically generated by
#   mduem and they are temporary ones.
#   Example: test/,good-case.output
#
# - Use directory ".mduem" to contain stuffs for internal use.
#   Example: .mduem/cache/
#
# - All rules may be violated if there is a strong custom from old times.
#   Example: all (phony target)








# Common  #{{{1

all: # Ensure that this is the default target.
