dnl Process this file with autoconf to produce a configure script.
dnl Some help with the syntax:
dnl AS_IF(test, body [, test, body]* [, body])
dnl All tests are executed in order until one returns true, then
dnl the corresponding body is executed, if no tests succeed, the
dnl last body (if present) is executed.
dnl This translates to a shell if statement with a bunch of elif
dnl clauses and an else clause.
dnl AS_CASE(word [, pattern, body]* [,body])
dnl The word is tested against each successive pattern, the body
dnl of the first matching pattern is executed, if no patterns
dnl match, the final body (if present) is executed.
dnl This translates to a shell case command with patterns and
dnl bodies, the final body gets the pattern *.
dnl AS_VERSION_COMPARE(version1, version2, lt-body, eq-body, gt-body)
dnl The two versions are compared, the body corresponding with
dnl whether the first version is less than, equal to, or greater
dnl than the second version is executed.
dnl AS_VAR_IF(var, word, eq-body, ne-body)
dnl If $var is equal to word, execute eq-body, else execute ne-body.
dnl @%:@
dnl This is a quadrigraph for #. We use this in C preprocessor
dnl code that we inline in the script so that it doesn't get
dnl confused with a start-of-comment.
dnl Note that by using this syntax, there should not be any
dnl unbalanced parentheses (due to there not being loose case
dnl statements). This makes editing easier.
dnl Also note that comments that start with # are copied to the
dnl configure file, whereas comments starting with dnl are elided
dnl (including their trailing newline).
