$(kpseinclude_HEADERS): paths.h

## First null out comments and leading/trailing whitespace, then remove
## lines that define invalid C identifiers, then remove blank lines and
## lines that define lowercase values (those are never path values). Each
## line remaining looks like
## <name> = <value>
## (but = and surrounding spaces are optional, hence can't remove all spaces).
## Change this to #ifndef DEFAULT_name@#define DEFAULT_name "value"@#endif,
## then change the @'s to newlines (sed isn't good at multiline replacements).
## 
## No backslash-newline escapes in the long sed replacement because that
## will turn into a space in the output.
## 
## We replace the $TEXMF* references with nonexisting directories.  These
## are the compile-time defaults and are not useful in the native TL
## builds; we rely completely on the self-location.  (Previously, the
## random build-time paths would get included in the binaries, to
## consequent confusion.)
## 
## We preserve the $SELFAUTO* references, since the selfauto-using
## compile-time path for cnf files is how texmf.cnf gets found, which
## determines everything else.
## 
## The definition of DEFAULT_TEXMF (and other variables)
## that winds up in the final paths.h will not be used.
#
## We don't want to rewrite paths.h when we have only changed comments
## in texmf.cnf that have no effect on paths.h, since that would cause
## almost everything to be rebuilt.
#
## We also replace all semicolons with colons in the paths.
## The path-splitting code should be changed to understand both.
