26 Rem Invoke like this:
\r
28 Rem djunpack bison-XYZ.tar.gz
\r
30 Rem djunpack bison-XYZ.tar.bz2
\r
32 Rem where XYZ is the version number. If the argument includes leading
\r
33 Rem directories, it MUST use backslashes, not forward slashes.
\r
36 set ENVIRONMENT_SIZE_TEST_STRING=ENVIRONMENT_SIZE_TEST_STRING

37 if "%ENVIRONMENT_SIZE_TEST_STRING%"=="ENVIRONMENT_SIZE_TEST_STRING" GoTo EnvOk
\r
38 Rem If their environment space is too small, re-exec with a larger one

39 command.com /e:4096 /c %0 %1

43 set ENVIRONMENT_SIZE_TEST_STRING=

\r
46 Rem Extract top src dir from archive file.
\r
47 djtar -t %1 > top_src.dir
\r
48 Rem The following uses a feature of COPY whereby it does not copy
\r
49 Rem empty files. We need that because the previous line will create
\r
50 Rem an empty fnchange.tmp even if the command failed for some reason.
\r
51 copy top_src.dir junk.tmp > nul
\r
52 if not exist junk.tmp GoTo NoDjTar
\r
54 sed "1{s/^.*bison-/djtar -x -p -o bison-/;s|$|djgpp/fnchange.lst %%1 > fnchange.tmp|};2,$d" top_src.dir > ext_list.bat
\r
55 Rem See the comment above about the reason for using COPY.
\r
56 copy ext_list.bat junk.tmp > nul
\r
57 if not exist junk.tmp GoTo NoSed
\r
59 Rem Extract fnchange.lst from archive.
\r
60 call ext_list.bat %1
\r
62 sed "1{s|^.*bison-|s/@V@/bison-|;s|$|g|};2,$d" top_src.dir > version.sed
\r
63 sed -f version.sed < fnchange.tmp > fnchange.lst
\r
67 Rem unpack the source distribution
\r
68 djtar -x -n fnchange.lst %1
\r
74 echo FAIL: Sed is not available.
\r
78 echo FAIL: DJTAR is not available or no fnchange.lst file in %1.
\r
81 echo FAIL: the file %1 does not seem to exist.
\r
82 echo Remember that %1 cannot use forward slashes, only backslashes.
\r
85 echo FAIL: no archive file has been specified.
