(Last checked against version &automake-contversion;.) acinstall is a script which installs aclocal-style M4 files. automake includes a number of autoconf macros which can be used in packages, some of which are needed by automake in certain situations. These macros must be defined in the aclocal.m4-file or they will not be seen by autoconf. The aclocal program will automatically generate aclocal.m4 files based on the contents of configure.in. This provides a convenient way to get automake-provided macros without having to search around. Also, the aclocal mechanism is extensible for use by other packages. To create all the Makefile.in files for a package, run the automake program in the top level directory, with no arguments. automake will automatically find each appropriate Makefile.am (by scanning configure.in) and generate the corresponding Makefile.in. compile is script which acts as a wrapper for compilers. config.guess is a script which attempts to guess a canonical system name. config.sub is a configuration validation subroutine script. depcomp is a script which compiles a program while generating dependencies as side-effects. elisp-comp is a script which byte-compiles .el files. install-sh is a script which installs a program, script, or a datafile. mdate-sh is a script which prints the modification time of a file or directory. missing is a script which acts as a common stub for a few missing GNU programs during an installation. mkinstalldirs is a script which makes a directory hierarchy. py-compile is a script which compiles a Python program. ylwrap is a script which acts as a wrapper for lex/yacc invocations.
