- # SYNOPSIS
- #
- # AX_MISSING_PROG(VARIABLE,PROGRAM,[MESSAGE])
- #
- # DESCRIPTION
- #
- # Simple wrapper for the AM_MISSING_PROG which displays a warning MESSAGE
- # if provided. A typical use is the following:
- #
- # AC_PROG_AWK
- # AS_IF([test -z "$AWK"],[
- # AX_MISSING_PROG(AWK,[awk],[awk seems missing ...])
- # ])
- #
- # Programs wrapped with AX_MISSING_PROG should be used only in the package
- # building phase (because they will be wrapped with the automake 'missing'
- # script, which will not be installed).
