Configuration file management
=============================
An easy but slightly too cumbersome to use tool to store & synchronize various
configuration files across multiple machines.
Actual configuration files are stored somewhere else (in a separate repository
perhaps) in directories which names must roughly match the `%.+%` regular
expression.
The part between the percent signs is the name of an environment variable.
Every file in such directory gets a symlink in the directory pointed to by the
environment variable.
Directory hierarchies are preserved.
For example, here's a possible representation of the "%PROGRAMDATA%" directory:
%PROGRAMDATA%/
└── a
└── b
└── c
└── test.txt
This tool would create a symlink "C:\ProgramData\a\b\c\test.txt" pointing to
"%PROGRAMDATA%\a\b\c\test.txt", wherever "%PROGRAMDATA%" is stored.
A database of symlinks is maintained in case a configuration file is deleted
(the corresponding symlink is then deleted too).
Default database file name is "db.bin".
Usage
-----
usage: update.sh [-d|--database PATH] [-s|--source DIR] [-n|--dry-run] [-h|--help]
To update the symlinks, run `./update.sh -d test.bin -s test`, substituting the
database file name for `test.bin` and directory path for `test`.
Requires Cygwin.
Limitations
-----------
Only alphanumeric variable names are supported.
Speaking more precisely, directory names must match the
`^%[_[:alpha:]][_[:alnum:]]*%$` regular expression.
This means that, for example, the environment variable `ProgramFiles(x86)` is
not supported.
