XX.SH NAME
XXmakedep - make dependency generator
XX.SH SYNOPSIS
XX.B makedep
XX.SP r rules ]
XX.SP R rules ]
XX.SP I list ]
XX.SP a list ]
XX.SF i
XXsourcefiles
XX.SH DESCRIPTION
XX.I Makedep
XXexamines the given source files,
XXand extracts all C preprocessor include statements
XXof the standard form
XX.IP
XX #include "file"
XX.br
XX #include <file>
XX.P
XXwith possible extra white space and trailing comments.
XXThe include statements are piped to
XX.I makenorm,
XXwhich transforms them into the normal form
XX.IP
XX file1 < file2
XX.P
XXWhen the top directory of a system is moved to a new position
XXin a global file system, all
XX.I make
XXdependencies should still be valid.
XXThe file names must therefore be expressed in a form
XXthat is insensitive to relocation.
XXIn most cases,
XXfile references relative to the current
XX.I make
XXdirectory have this property.
XXSome references, however, are global in nature.
XXThe dependency
XX.IP
XX prog.o: ../../../../../../usr/include/time.h
XX.P
XXbecomes invalid when the system is moved downwards in
XXa file system.
XX.P
XXTherefore, whenever a file name refers to an absolute directory,
XXit is expressed in absolute form,
XXotherwise it is made relative to the given
XX.I make
XXdirectory.
XXThe directory
XX.I /usr/include
XXis always considered absolute,
XXbut additional absolute directories may be specified.
XX.P
XXThe normalized include statements are, in turn,
XXpiped to
XX.I depend,
XXwhich generates all
XX.I make
XXdependencies implied by the include statements.
XX.P
XXThe resulting dependencies are written to the standard output.
XX.P
XXInclude file references are normally interpreted by
XXthe C preprocessor as relative to
XXthe directory of the file in which the statement occurred.
XXHowever, if the referenced file cannot be found,
XXa user directory list is first searched, if specified,
XXand then the system directory
XX.I /usr/include.
XXThe '#include <file>' form searches only the user list
XXand the system directory.
XX.P
XXGenerated files may be missing or obsolete
XXat the time of the
XX.I make
XXdependency generation,
XXso include statements must extracted from source files.
XXHowever, include statements may reference generated files,
XXlike e.g. a
XX.I lex
XXgenerated 'scanner.c' which is included in a
XX.I yacc
XXfile.
XXTherefore, a set of standard include suffix rules
XXare used to deduce which files will be present at
XXC compile time,
XXand all implied
XX.I make
XXdependencies may thus be generated by examining
XXthe source files
XX(see the SP & E article below).
XX.P
XXSince include statements are sometimes propagated
XXto more than one output file,
XXparallell transfer rules are permitted.
XXFor example, the
XX.B -d
XXoption to
XX.I yacc
XXproduces a definitions file,
XXwhich may be referenced by other files.
XX.P
XXTo make automatic dependency generation possible,
XX.I yacc
XXoutput files must have the same base name as the
XXinput file.
XXThus, if the
XX.I make
XXdependencies and corresponding commands are written:
XX.IP
XX grammar.h grammar.c: grammar.y
XX.br
XX yacc -d grammar.y
XX.br
XX mv y.tab.c grammar.c
XX.br
XX mv y.tab.h grammar.h
XX.P
XXthe default parallell rules
XX.IP
XX .c= .y
XX.br
XX .h= .y
XX.P
XXwill be applicable.

XX.SH NAME
XXmakenorm - include statement normalizer
XX.SH SYNOPSIS
XX.B makenorm
XX.SP r rules ]

XX.SP I list ]
XX.SP a list ]
XX.SF i
XXmakedir
XXsourcefiles
XX.SH DESCRIPTION
XX.I Makenorm
XXaccepts C preprocessor include statements
XXof the form
XX.IP
XX file1: #include "file"
XX.br
XX file2: #include <file>
XX.P
XXfrom the standard input
XXwith possible extra white space and trailing comments,
XXand writes them to the standard output in the normal form
XX.IP
XX file1 < file2
XX.P
XXThis form is suitable for later processing by the
XX.I depend
XXcommand to generate
XX.I make
XXdependencies.
XX.P
XXWhen the top directory of a system is moved to a new position
XXin a global file system, all
XX.I make
XXdependencies should still be valid.
XXThe file names must therefore be expressed in a form
XXthat is insensitive to relocation.
XXIn most cases,
XXfile references relative to the current
XX.I make
XXdirectory have this property.
XXSome references, however, are global in nature.
XXThe dependency
XX.IP
XX prog.o: ../../../../../../usr/include/time.h
XX.P
XXbecomes invalid when the system is moved downwards in
XXa file system.
XX.P
XXTherefore, whenever a file name refers to an absolute directory,
XXit is expressed in absolute form,
XXotherwise it is made relative to the given
XX.I make
XXdirectory.
XXThe directory
XX.I /usr/include
XXis always considered absolute,
XXbut additional absolute directories may be specified.
XX.P
XXWhether a reference is absolute or not,
XXit is always reduced to the shortest possible path
XX(loops eliminated),
XXso that file names can later be unambiguously identified by the
XX.I depend
XXcommand.
XX.P
XXInclude file references are normally interpreted by
XXthe C preprocessor as relative to
XXthe directory of the file in which the statement occurred.
XXHowever, if the referenced file cannot be found,
XXa user directory list is first searched, if specified,
XXand then the system directory
XX.I /usr/include.
XXThe '#include <file>' form searches only the user list
XXand the system directory.
XX.P
XXGenerated files may be missing or obsolete
XXat the time of the

XXso include statements must extracted from source files.
XXHowever, include statements may reference generated files,
XXlike e.g. a
XX.I lex
XXgenerated 'scanner.c' which is included in a
XX.I yacc
XXfile.
XXTherefore, a set of standard include suffix rules
XXare used to deduce,
XXfrom the given list of source files,
XXwhich files will be present at C compile time
XX(see the SP & E article below).
XXInclude file references are thus resolved without requiring
XXany of the files to be present when
XX.I makenorm
XXis run.
XX.P
XXArguments:
XX.A1 r rules The
XXstandard include suffix rules
XX.IP
XX .o: .c .p .f
XX.br
XX .c= .y .l .q
XX.br
XX .h= .y

XXThe argument is a string of rules, separated by semicolon.
XX.A1 R rules The

XX.A1 I list Add
XXthe specified directories to the

XX.SH SYNOPSIS
XX.B depend
XX.SP r file ]
XX.SP R rules ]
XX.SF 1
XX.SH DESCRIPTION
XX.I Depend
XXaccepts lines of the form
XX.IP
XX file1 < file2
XX.P
XXfrom the standard input.
XXThe lines represent include statements
XXextracted from source files.
XXEach file name is assumed to be in normal form,
XXi.e., shortest absolute path for files
XXin absolute directories,
XXand shortest path relative to the make directory
XXfor all other files.
XX.P
XXThe
XX.I make
XXdependencies implied by these
XXinclude statements
XXare output in the form
XX.nf
XX.IP
XX fileX1: fileX2 fileX3 fileX4 ...
XX fileY1: fileY2 fileY3 fileY4 ...
XX ...
XX.fi
XX.P
XXto the standard output.
XXIf a dependency line is longer than 80 characters,
XXit is split into two lines,
XXso the generated dependencies can be conveniently
XXinspected from a crt terminal.
XX.P
XXArguments:
XX.A1 r rules The
XXstandard include suffix rules
XX.IP
XX .o: .c .p .f
XX.br
XX .c= .y .l .q

XXThe argument is a string of rules, separated by semicolon.
XX.A1 R rules The
XXstandard include suffix rules are replaced by

XX.AR 1 Only one dependency per output line.
XXThis is useful for postprocessing,
