| 1588 | This installation shell script will examine your system and ask you questions |
| 1589 | to determine how the perl5 package should be installed. If you get |
| 1590 | stuck on a question, you may use a ! shell escape to start a subshell or |
| 1591 | execute a command. Many of the questions will have default answers in square |
| 1592 | brackets; typing carriage return will give you the default. |
| 1593 | |
| 1594 | On some of the questions which ask for file or directory names you are allowed |
| 1595 | to use the ~name construct to specify the login directory belonging to "name", |
| 1596 | even if you don't have a shell which knows about that. Questions where this is |
| 1597 | allowed will be marked "(~name ok)". |
| 1598 | |
| 1599 | EOH |

| 1603 | cat <<'EOH' |
| 1604 | |
| 1605 | The prompter used in this script allows you to use shell variables and |
| 1606 | backticks in your answers. You may use $1, $2, etc... to refer to the words |
| 1607 | in the default answer, as if the default line was a set of arguments given to a |
| 1608 | script shell. This means you may also use $* to repeat the whole default line, |
| 1609 | so you do not have to re-type everything to add something to the default. |
| 1610 | |
| 1611 | Everytime there is a substitution, you will have to confirm. If there is an |
| 1612 | error (e.g. an unmatched backtick), the default answer will remain unchanged |
| 1613 | and you will be prompted again. |
| 1614 | |
| 1615 | If you are in a hurry, you may run 'Configure -d'. This will bypass nearly all |
| 1616 | the questions and use the computed defaults (or the previous answers if there |
| 1617 | was already a config.sh file). Type 'Configure -h' for a list of options. |
| 1618 | You may also start interactively and then answer '& -d' at any prompt to turn |
| 1619 | on the non-interactive behaviour for the remainder of the execution. |

| 1625 | Much effort has been expended to ensure that this shell script will run on any |
| 1626 | Unix system. If despite that it blows up on yours, your best bet is to edit |
| 1627 | Configure and run it again. If you can't run Configure for some reason, |
| 1628 | you'll have to generate a config.sh file by hand. Whatever problems you |
| 1629 | have, let me (jhi@iki.fi) know how I blew it. |
| 1630 | |
| 1631 | This installation script affects things in two ways: |
| 1632 | |
| 1633 | 1) it may do direct variable substitutions on some of the files included |
| 1634 | in this kit. |
| 1635 | 2) it builds a config.h file for inclusion in C programs. You may edit |
| 1636 | any of these files as the need arises after running this script. |
| 1637 | |
| 1638 | If you make a mistake on a question, there is no easy way to back up to it |
| 1639 | currently. The easiest thing to do is to edit config.sh and rerun all the SH |
| 1640 | files. Configure will offer to let you do this before it runs the SH files. |

| 4523 | is a time consuming task which may generate huge output on the disk (up |
